CCD-based observations of PG 0856+121 and a theoretical analysis of its oscillation modes.

ULLA A., ZAPATERO OSORIO M.R., PEREZ HERNANDEZ F. and MacDONALD J.

Abstract (from CDS):

BVRI CCD-based and near-IR (J) imaging, together with unfiltered photometry of the hot subdwarf B star PG 0856+121, are reported. Two close, faint, red, point-like sources are resolved. They account for the previously reported IR excess observed in this hot subdwarf. In addition, the new unfiltered differential photometry of PG 0856+121 confirms its previously reported pulsational nature. A comparison with the oscillation modes of stellar models suggests the presence of g modes.
