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…
