PG 1618 + 563 B : A new bright pulsating sdB star ?
The results of two runs of time-series photometry made at the Nordic Optical Telescope clearly show that the sdB star PG 1618+563B is a new member of the EC 14026 class of sdB pulsators. Its power spectrum shows a doublet of frequencies at about 6.95 and 7.18 mHz (P ∼ 144 and 139 s respectively), which produce a modulation effect in the light curve with a beat period of about 1.2 hours. The amp...
متن کاملA New, Bright, Short-Period, Emission Line Binary in Ophiuchus
The 11th magnitude star LS IV−083 has been classified previously as an OB star in the Luminous Stars survey, or alternatively as a hot subdwarf. It is actually a binary star. We present spectroscopy, spectroscopic orbital elements, and time series photometry, from observations made at the Kitt Peak National Observatory 2.1m, Steward Observatory 2.3m, MDMObservatory 1.3m and 2.4m, Hobby-Eberly 9...
متن کاملElectronic Spectral Line Shape of a Diatomic Molecule
The electronic absorption spectral line shape of a diatomic molecule with harmonic potential curves is calculated using the time correlation function formalism. Both the equilibrium shift and the frequency shift of the two linking electronic states ate taken into account. The spectrum is also calculated using the cumulated expansion which is related to the correlation function of the time-d...
