Brightest stars in the night sky can strip planets to their rocky cores

UC Berkeley astronomers have discovered a hard-to-find gas giant around one of these bright, but short-lived, stars, right at the edge of the hot Neptune desert where the star’s strong radiation likely strips any giant planet of its gas.
