Magnetic field geometries of two slowly rotating Ap / Bp stars : HD 12288 and HD 14437
In this paper we report magnetic field models and basic physical parameters for the slowly rotating Ap/Bp stars HD 12288 and HD 14437. Using new and previously published mean longitudinal magnetic field, mean magnetic field modulus, and hipparcos photometric measurements, we have inferred the rotational periods of both stars (HD 12288: Prot = 34. d9 ± 0. d2; HD 14437: Prot = 26. d87 ± 0. d02). ...
متن کاملLine profile variability in the spectra of Oef stars : II . HD 192281 , HD 14442 and HD 14434 ⋆
We present the very first analysis of the spectroscopic variability of the three rapidly rotating Oef stars HD 192281 (O5(ef)), HD 14442 (O5.5ef) and HD 14434 (O6.5(ef)). Radial velocities of the He II λ 4541 line reveal no evidence of binarity on time scales of a few days, or from one year to the next, for any of the targets. The He II λ 4686 double-peaked emission and, to some extent, the Hβ ...
متن کاملThe magnetic field of the CP star HD 119419
We present a detailed model for the magnetic field of the chemically peculiar star HD 119419 consistent with five different kinds of observational constraint: mean longitudinal field, crossover, mean quadratic field, projected equatorial velocity and stellar radius. The stellar surface presents a complex magnetic structure originated by a 17 kG dipole superposed to a 48 kG quadrupole, and inclu...
متن کاملDiscovery of unusual pulsations in the cool , evolved Am stars HD 98851 and HD 102480
The chemically peculiar (CP) stars HD98851 and HD102480 have been discovered to be unusual pulsators during the “Naini Tal Cape Survey” programme to search for pulsational variability in CP stars. Time series photometric and spectroscopic observations of these newly discovered stars are reported here. Fourier analyses of the time series photometry reveal that HD98851 is pulsating mainly with fr...
متن کاملDiscovery of Close Companions to the Nearby Young Stars Hd 199143 and Hd 358623
Young stellar systems in the solar neighborhood provide valuable laboratories for detailed studies of star and planet formation. The bright F8V star HD 199143 and the Li-rich late-type emission line star HD 358623 are among the nearest young stars identified to date, and may be members of a young association in Capricornus. We present high-resolution near-infrared images of these two sources, o...
