What can binary stars comprised of two different types of stars teach astronomers about stellar evolution? This is what a recent study published in The Astrophysical Journal hopes to address as a team ...

Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...

Despite having recently officially ended its science operations in January, Gaia, one of the most prolific star explorers ever, is still providing new scientific insights. A recent paper submitted to ...

Astronomers at the University of Toronto (U of T) have discovered the first pairs of white dwarf and main sequence stars—"dead" remnants and "living" stars—in young star clusters. Described in a new ...

For a star, its initial mass is everything. It determines how quickly it burns through its hydrogen and how it will evolve once it starts fusing heavier elements. It’s so well understood that ...

This image from the ALMA telescope shows star system HD101584 and the complex gas clouds surrounding the binary. It is the result of a pair of stars sharing a common outer layer during their last ...
