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 ...

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, ...

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

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

Among the roughly 10 billion white dwarf stars in the Milky Way galaxy, a greater number than previously expected could ...

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 ...

Infant stars, or "protostars," haven't yet gathered enough mass to trigger the nuclear fusion of hydrogen to helium in their cores, the process which defines what a main sequence star is.

Scientists have long overlooked white dwarfs as hosts for habitable exoplanets, assuming their lack of fusion would make life impossible. But new climate models challenge that idea, showing that ...

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 ...
