Measuring masses of transiting Earth-like planets: first insights from the PLATO RV data challenge
M. Cretignier, N. C. Hara, S. Aigrain +24
The PLATO Stellar Variability Mitigation Working Group designed a radial-velocity (RV) data challenge to assess the precision and accuracy achievable on RV semi-amplitudes in the c…
Stellar surface information from the Ca II H&K lines -- II. Defining better activity proxies
M. Cretignier, N. C. Hara, A. G. M. Pietrow +6
In our former paper I, we showed on the Sun that different active regions possess unique intensity profiles on the Ca II H & K lines. We now extend the analysis by showing how thos…
New Compact Object Binary Populations with Precision Astrometry (Roman White Paper)
P. Gandhi, C. Dashwood Brown, Y. Zhao +6
Compact object binaries (a black hole or a neutron star orbiting a non-degenerate stellar companion) are key to our understanding of late massive star evolution, in addition to bei…
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…
Astrometric excess noise in Gaia DR2 and the search for X-ray emitting binaries
Poshak Gandhi, David A. H. Buckley, Phil Charles +4
Astrometric noise in excess of parallax and proper motion could be a signature of orbital wobble of individual components in binary star systems. The combination of X-ray selection…
