Discovery and asteroseismological analysis of a new pulsating DB white dwarf star, PG 2246+121.
HANDLER G.
Abstract (from CDS):
We argue that these multiplets are the result of non-radial g-mode pulsations, most probably of spherical degree ℓ=1, which then yields a formal stellar rotation period of 2.00±0.12d. We suggest that the excited modes are three consecutive radial overtones of order 3-7, most likely k=4,5,6. This discovery's impact on the understanding of pulsating DB white dwarfs is discussed.
