How much can we trust high-resolution spectroscopic stellar chemical abundances?
S. Blanco-Cuaresma, T. Nordlander, U. Heiter +8
To study stellar populations, it is common to combine chemical abundances from different spectroscopic surveys/studies where different setups were used. These inhomogeneities can l…
How much can we trust high-resolution spectroscopic stellar atmospheric parameters?
S. Blanco-Cuaresma, T. Nordlander, U. Heiter +8
The determination of atmospheric parameters depends on the use of radiative transfer codes (among other elements such as model atmospheres) to compute synthetic spectra and/or deri…
The Solar Twin Planet Search: IV. The Sun as a typical rotator and evidence for a new rotational braking law for Sun-like stars
Leonardo A. dos Santos, Jorge Meléndez, José-Dias do Nascimento +8
It is still unclear how common the Sun is when compared to other similar stars in regards to some of its physical properties, such as rotation. Considering that gyrochronology rela…
High precision analysis of the solar twin HIP 100963
Jhon Yana Galarza, Jorge Meléndez, Ivan Ramírez +3
Methods. We used the HIRES spectrograph on the Keck I telescope to acquire high-resolution (R 70000) spectra with a high signal-to-noise ratio (S/N 400 - 650 pe…
A 12-Year Activity Cycle for HD 219134
Marshall C. Johnson, Michael Endl, William D. Cochran +8
The nearby (6.5 pc) star HD 219134 was recently shown by Motalebi et al. (2015) and Vogt et al. (2015) to host several planets, the innermost of which is transiting. We present twe…
The Curious Case of Elemental Abundance Differences in the Dual Hot Jupiter Hosts WASP-94AB
Johanna K. Teske, Sandhya Khanal, Ivan Ramírez
Binary stars provide an ideal laboratory for investigating the potential effects of planet formation on stellar composition. Assuming the stars formed in the same environment/from…
Two Hot Jupiters from K2 Campaign 4
Marshall C. Johnson, Davide Gandolfi, Malcolm Fridlund +20
We confirm the planetary nature of two transiting hot Jupiters discovered by the Kepler spacecraft's K2 extended mission in its Campaign 4, using precise radial velocity measuremen…
