Astrophysicists studying a popular exoplanet in its star's habitable zone have found that electric currents in the planet's upper atmosphere could create sufficient heating to expand the atmosphere enough that it leaves the ...
A team with members from institutions across the U.S. has used an existing solar model to predict the ability of exoplanets to withstand localized stellar wind. In their paper published in Proceedings of the National Academy ...
Astronomers have observed directly for the first time how intense light from stars can 'push' matter. Researchers from the universities of Cambridge and Sydney made the observation when tracking a giant plume of dust generated ...

Astronomers from Austria and Northern Ireland have inspected a peculiar extreme helium supergiant star known as HD 144941. Results of the new study, published October 21 on the arXiv pre-print server, indicate that HD 144941 ...
New research led by NASA provides a closer look at a nearby star thought to resemble our young sun. The work allows scientists to better understand what our sun may have been like when it was young, and how it may have shaped ...

Using data from ESA's XMM-Newton and NASA's Swift spacecraft, astronomers have conducted a detailed temporal and spectral study of an eclipsing supergiant X-ray binary known as IGR J18027–2016. Results of this research ...
Astronomers have presented an explanation for the shapes of planetary nebulae. The discovery is based on a set of observations of stellar winds around aging stars. Contrary to common consensus, the team found that stellar ...
