New observations provide insights into whether the birth of the giant planets takes a similar course to that of stars. The birth of stars is…
Scientists have discovered that some white dwarfs stop cooling due to internal crystal formation, challenging existing theories on star aging and affecting stellar age estimation…
At least one in a dozen stars show evidence of planetary ingestion. At least one in a dozen stars show evidence of planetary ingestion according…
Recent findings show some white dwarf stars halt their cooling due to gravitational energy release, overturning the belief that these stars are simply cooling remnants…
New research reveals that white dwarf stars stop cooling due to floating crystals in their interior, offering insights into stellar aging processes. In a paper…
Researchers discovered why some white dwarfs remain luminous for billions of years: a core process where lighter crystals rise and denser liquids sink, balancing the…
When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it….
Astronomers using Georgia State’s CHARA Array have detected the faint light of stellar corpses beside predator stars. Scientists working with the powerful telescopes at Georgia…
New types of stars, including ‘old smokers’ and erupting protostars, have been discovered in the Milky Way. This research, using advanced telescopes, challenges existing theories…
Through the study of detailed data obtained from a powerful ten-meter telescope located in Hawaii, a team of scientists at Lund University in Sweden have…
A newly developed technique for estimating age reveals surprising findings about the formation and drifting apart of young stars. A team of astrophysicists led by…
Gyrochronology, a technique for estimating star ages based on rotation, has been extended from cluster stars to field stars, revealing consistent aging patterns and broadening…
New findings confirm existence of hot helium stars long-thought to be at the heart of hydrogen-poor supernovae and neutron star mergers. Astronomers at the University…
A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research…
Uncovering the missing precursors of hydrogen-poor supernovae. Supernovae–stellar explosions as bright as an entire galaxy–have fascinated us since time immemorial. Yet, there are more hydrogen-poor…
New study is the first to determine how much stars should innately twinkle. Many people know that stars appear to twinkle because our atmosphere bends…
Astronomers have mapped 39 interstellar clouds where high-mass stars are expected to form. This extensive data indicates that our current understanding of low-mass star creation…
