Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected three companions to aged stars—two low-mass stars and one brown dwarf. The newfound objects are the size of Jupiter ...
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 ...
