The Distribution of Main Sequence and Premain Sequence Stars in the Young Anticenter Cluster NGC 2401 ... PMS stars can be matched by a model that assumes a solar neighborhood mass function, ...

Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

The strange behavior of hypervelocity stars suggests a nearby dwarf galaxy must contain a supermassive black hole. If so, a ...

Uncertainties about the true distances and masses of these high‐latitude B stars have ... to the conclusion that the B stars in this system are massive young main‐sequence stars. While there are ...

"This is the first solid evidence that helical magnetic fields can explain astrophysical jets at different scales." ...

They simulated 2522 planets that orbited 500 stars ... main sequence stars have produced free-floating planets. The team’s simulations allowed for four, five or size planets per star ranging in ...

while its mass is approximately 0.096 solar masses—therefore close to the hydrogen burning limit and the boundary between main sequence stars and brown dwarfs. The M dwarf orbits the primary ...

UC Irvine astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would ...
