The Ap Star Hd 83368 May Be a Lithium-spotted Pulsator

چکیده
Several observations of some Ap stars have been made at the ESO, Nordic and Crimean telescopes in 1996. Interesting results have been found for the roAp star HD 83368 = HR 3831 in the Li spectral region. These have shown the presence of two almost diametrically opposed spots of Li or of the element responsible for the " Li " blend, which cause strong variations in the profile and position of the Li blend at 6708Å.

Lithium on the surface of cool magnetic CP stars I. Summary of spectroscopic observations with three telescopes
We present new results of observations of the 6708 Å line in twelve CP stars made with three telescopes: the ESO CAT telescope, the Crimean Observatory (CrAO) 2.6-m telescope, and the Nordic Optical Telescope (NOT). Unique profile and wavelength variations of the line at 6708 Å were discovered in two stars, HD 60435 and HD 83368. We present arguments in favour of the identification of this feat...
متن کاملTime - series spectroscopy of the rapidly oscillating Ap star HR 3831
We present time-series spectroscopy of the rapidly oscillating Ap star HR 3831. This star has a dominant pulsation period of 11.7 minutes and a rotation period of 2.85d. We have analysed 1400 intermediate-resolution spectra of the wavelength region 6100– 7100Å obtained over one week, using techniques similar to those we applied to another roAp star, α Cir. We confirm that the Hα velocity amplit...
متن کاملConfirmation of simultaneous p and g mode excitation in HD 8801 and γ Peg from time-resolved multicolour photometry of six candidate ”hybrid” pulsators
We carried out a multi-colour time-series photometric study of six stars claimed as ”hybrid” p and g mode pulsators in the literature. γ Peg was confirmed to show short-period oscillations of the β Cep type and simultaneous long-period pulsations typical of Slowly Pulsating B (SPB) stars. From the measured amplitude ratios in the Strömgren uvy passbands, the stronger of the two short period pul...
متن کاملThe Ap spectroscopic binary HD 59435 revisited ? , ? ?
HD 59435 is a double-lined spectroscopic binary, one component of which is a magnetic Ap star and the other a G8 or K0 giant (Wade et al. 1996). Both components are very slowly rotating, and the Ap star exhibits spectral lines resolved into their magneti cally-split components. Herein we report additional measurements of the mean magnetic field modulus of the Ap star, measurements of the radial...
متن کاملHD 12098 and Other Results from Naini Tal - Cape Survey
Naini Tal-Cape Survey is a survey started with the aim of searching for new rapidly oscillating Ap stars in the northern hemisphere and has discovered one mono-periodic roAp star HD 12098. The frequency separation of HD 12098 suggests a rotation period of 5.5 day for the star. The discovery of roAp oscillations in HD 12098 and the results of the multi-site observation campaign organized to reso...
