In today’s paper, the authors use Cepheid distance moduli to study the structure of the SMC.
Stars form via gravitational collapse of molecular cloud cores. But observations reveal that far less gas is turned into stars than you would suspect by naively calculating the star formation rate. So what can we do about this mismatch?
Heavy stars live like rock stars: they live fast, become big, and die young. Low mass stars, on the other hand, are more persistent, and live longer. Fusing hydrogen slow and steady wins the stellar age-race.
Nothing sits still in our Universe. Like planets, stars rotate. The authors of this paper found certain types of stars unexpectedly display rapid rotations when they are not supposed to.
A star on its way out of the Milky Way has set a new speed record. What’s the rush? Read on to find out…
While the Sun is an excellent starting point in a quest to understand magnetism, the authors of today’s paper want more. They take advantage of something only relatively cool stars can have in their atmospheres to study magnetic fields: molecules in starspots.
