HS 0702+6043: a star showing both short-period <i>p</i>-mode and long-period <i>g</i>-mode oscillations

Abstract

Context.The hot subdwarf B star HS 0702+6043 is known as a large-amplitude, short-period p-mode pulsator of the EC 14026 type. Its atmospheric parameters place it at the common boundary between the empirical instability regions of the EC 14026 variables and the typically cooler long-period g-mode pulsators of the PG 1716 kind.
