A new model that has attained 99.45% precision has been used to identify 4,383 carbon stars, including 1,197 newly identified as such, out of 11,226,252 stars in the LAMOST sample
A young white dwarf may have recently transferred 0.15 solar mass of matter to its binary companion, creating a barium blue straggler star that was identified by its unusual chemical composition.
Newly spliced-together “Frankenspectra” spanning mid-infrared to far-ultraviolet wavelengths have been made available online and will aid in the study of dust on planetary bodies.
The IceCube Neutrino Observatory did not detect any discrete neutrino flares between 2011 and 2021; hundreds or thousands of flares are needed to explain the diffuse neutrino flux.
Researchers got a new look at the famous directly imaged giant exoplanet beta Pictoris b; the new data confirm the confusing mismatch between the planet’s dynamical mass and mass implied by models.
Sub-Neptune GJ 1214b total envelope mass fraction has been constrained to be at least 8.1% to match observations, but the composition could be various combinations of rock, ice, and volatiles.
