Measuring precise radial velocities on individual spectral lines. III. Dependence of stellar activity signal on line formation temperature
K. Al Moulla, X. Dumusque, M. Cretignier +2
Context. To enable radial velocity (RV) precision on the order of ~0.1 m/s required for the detection of Earth-like exoplanets orbiting solar-type stars, the main obstacle lies in…
Rotation in the Pleiades with K2: II. Multi-Period Stars
L. M. Rebull, J. R. Stauffer, J. Bouvier +15
We use K2 to continue the exploration of the distribution of rotation periods in Pleiades that we began in Paper I. We have discovered complicated multi-period behavior in Pleiades…
Rotation in the Pleiades with K2: I. Data and First Results
L. M. Rebull, J. R. Stauffer, J. Bouvier +16
Young (125 Myr), populous (1000 members), and relatively nearby, the Pleiades has provided an anchor for stellar angular momentum models for both younger and older stars. We use…
Three-dimensional magnetic and abundance mapping of the cool Ap star HD 24712 I. Spectropolarimetric observations in all four Stokes parameters
N. Rusomarov, O. Kochukhov, N. Piskunov +8
High-resolution spectropolarimetric observations provide simultaneous information about stellar magnetic field topologies and three-dimensional distributions of chemical elements.…
First detection of linear polarization in the line profiles of active cool stars
O. Kochukhov, V. Makaganiuk, N. Piskunov +6
The application of high-resolution spectropolarimetry has led to major progress in understanding the magnetism and activity of late-type stars. During the last decade, magnetic fie…
The search for magnetic fields in mercury-manganese stars
V. Makaganiuk, O. Kochukhov, N. Piskunov +7
We performed a highly sensitive search for magnetic fields on a large set of HgMn stars. With the aid of a new polarimeter attached to the HARPS spectrometer at the ESO 3.6m-telesc…
The Metallicity of the HD 98800 System
Tanmoy Laskar, David R. Soderblom, Jeff A. Valenti +1
Pre-main sequence (PMS) binaries and multiples enable critical tests of stellar models if masses, metallicities, and luminosities of the component stars are known. We have analyzed…
