Twin Stars and Celestial Cannibalism
Tag: GS-3 Science and Tech.
In News: Researchers recently examined 91 pairs of stars originating from the same stellar nursery, possessing comparable sizes and compositions.
Stability of Planetary Systems
- Earth’s solar system has remained stable over its 4.5 billion years.
- A new study reveals instability in other planetary systems, particularly those with twin stars.
- An international team used large telescopes to observe 91 pairs of twin stars, finding evidence of planets being ‘ingested.’
Discovery of Cosmic Cannibalism
- Among the studied twin stars, approximately eight percent showed compositional differences.
- One star in each pair displayed a tendency to ‘devour’ planets or planetary material.
- This phenomenon of cosmic cannibalism was observed in seven out of the 91 pairs of twin stars.
Characteristics of Twin Stars
- Twin stars formed from the same interstellar cloud, sharing the same chemical makeup, mass, and age.
- While moving together within the Milky Way Galaxy, these pairs are not binary systems gravitationally bound to each other.
Reasons Behind Cosmic Cannibalism
- Potential causes include orbital disturbances caused by larger planets or passing stars destabilizing the planetary system.
- Observations were made using the Gaia space observatory and telescopes in Chile and Hawaii.
Implications and Significance
- Stars observed ranged from 70 to 960 light years away from our solar system.
- While mostly indicating whole planets being ingested, it’s possible planetary building blocks were consumed during system formation.
- This phenomenon suggests a non-negligible fraction of planetary systems may be unstable, with planets being ejected or ingested by host stars.
- The study implies that there may be more planetary exiles than previously estimated, with potential implications for our understanding of planetary formation and evolution.

White Dwarfs
Tag: GS-3 Science and Tech.
In News: Astronomers have announced the identification of four white dwarf stars belonging to a newly found and uncommon DAQ spectral subgroup.
Overview of White Dwarfs
- White dwarfs are remnants of dying stars that have exhausted their nuclear fuel and shed their outer layers to form a planetary nebula.
- They represent the final stage in the evolution of stars like the Sun after they have consumed their nuclear fuel.
- Despite no longer undergoing nuclear fusion reactions, white dwarfs remain incredibly hot.
- Typically, white dwarfs are about half as massive as the Sun but only slightly larger than Earth, making them one of the densest forms of matter, surpassed only by neutron stars.
- Newly formed white dwarfs consist mainly of helium, carbon, and oxygen nuclei surrounded by highly energetic electrons.
- Unlike other stars supported by normal gas pressure, white dwarfs are upheld by the degeneracy pressure of their electron gas.
- Over time, white dwarfs cool down unless they are accreting matter from nearby stars.
- Eventually, white dwarfs are expected to evolve into “black dwarfs,” although the universe may not yet be old enough for any to exist.
- The luminosity of white dwarfs serves as a valuable tool for astronomers to measure the age of star formation in specific regions.
- Many young white dwarfs emit soft X-rays, providing insight into their formation and evolution.
- White dwarfs also act as “fossil” records of the stars from which they originated, aiding in cosmological studies.
- In 2006, the Hubble Space Telescope observed white dwarfs in globular star clusters, identifying them as the dimmest stars ever observed in such clusters.

Snowpacks
Tag: GS-1 Physical Geography
In News: Scientists have developed a novel method for quantifying the volume of water stored in snowpacks and determining its duration.
Overview of Snowpacks
- In regions with winter seasons and mountainous terrain, precipitation falls as snow.
- Snow that remains on the ground for extended periods due to below-freezing temperatures is known as a snowpack.
- Snowpacks comprise multiple layers of snow from different snowfall events, compacted under subsequent layers.
- They persist until spring when rising temperatures cause melting, resulting in snowmelt.
- Snowmelt serves as a crucial water source, sustaining streams and replenishing reservoirs.
- The depth of a snowpack is influenced by snowfall, temperature, and wind conditions.
- Strong winds can erode snow cover, while warmer temperatures accelerate melting.
- In suitable conditions, snowpacks can accumulate to depths exceeding three meters (10 feet).
- Snowpack density increases with more layers, exerting pressure on lower layers.
- Weak layers, like surface hoar, heighten the risk of avalanches.
- Snowpack data is essential for monitoring the impacts of climate change.

Ebola Virus Disease
Tag: GS-3 Science and Tech.
In News: Researchers have recently discovered a novel mechanism through which Ebola replicates within the human body, pinpointing a potential candidate for drug targeting to mitigate the viral infection.
Overview of Ebola Virus Disease (EVD)
- Ebola virus disease (EVD, or Ebola) is a rare yet severe illness affecting humans.
- It is caused by various species of viruses belonging to the genus Ebolavirus, primarily found in sub-Saharan Africa.
- The disease derived its name from the Ebola River, located near one of the villages in the Democratic Republic of Congo where it was initially identified.
- Transmission of Ebola:
- Ebola is not as easily transmissible as common viruses like colds, influenza, or measles.
- Transmission occurs through contact with the skin or bodily fluids of an infected animal, such as a monkey, chimp, or fruit bat.
- It can spread from person to person through similar means, often affecting caregivers or individuals involved in burial rites of deceased patients.
- Air, water, or food does not transmit the Ebola virus, and asymptomatic individuals cannot spread the disease.
- Symptoms of Ebola:
- Symptoms typically manifest within two to 21 days after viral exposure.
- Initially, symptoms resemble those of the flu but may progress to severe manifestations such as vomiting, bleeding, and neurological complications.
- Treatment and Management:
- Currently, there is no specific treatment for Ebola, although experimental vaccines and therapeutics are under investigation.
- Patient recovery may hinge on factors such as the initial viral exposure, prompt initiation of treatment, age, and immune response.
- Treatment mainly involves maintaining fluid and electrolyte balance and administering blood and plasma to manage bleeding.
- Mortality Rates:
- Mortality rates associated with EVD vary widely, ranging from 25 percent to 90 percent, with an average of around 50 percent.
- Fatalities typically result from shock induced by fluid loss rather than hemorrhaging.

Section 153A of the Indian Penal Code
Tag: GS-2 Polity
In News: The Supreme Court emphasized that for an offense to be established under Section 153A of the Indian Penal Code, the crucial element is the generation of animosity and discord among two or more groups or communities.
Overview of Section 153A of the IPC
- Section 153A of the IPC aims to prosecute individuals involved in inciting animosity among various groups based on factors such as religion, caste, race, place of birth, residence, or language.
- This provision holds accountable those who:
- Disseminate hatred through spoken or written words, visual representations, or symbols with the intent of sowing discord, hatred, or unrest among individuals of different groups, religions, castes, or communities.
- Foster disharmony and disrupt public peace among people of diverse racial and religious backgrounds.
- Assist in the organization of movements or drills that encourage and train participants to employ criminal force and violence against individuals from other racial and religious groups and communities.
- Covers offenses involving moral turpitude.
- Offenders may face a punishment of up to three years’ imprisonment, a fine, or both.
- However, if the offense occurs in a place of worship, the punishment may be extended to five years’ imprisonment along with a fine.
- Additionally, offenses under Section 153A are non-bailable, and the accused is tried by a first-class magistrate.
