New Mass and Radius Constraints on the LHS 1140 Planets -- LHS 1140 b is Either a Temperate Mini-Neptune or a Water World
Charles Cadieux, Mykhaylo Plotnykov, René Doyon +43
The two-planet transiting system LHS 1140 has been extensively observed since its discovery in 2017, notably with , HST, TESS, and ESPRESSO, placing strong constraints on…
Overview of semi-sinusoidal stellar variability with the CoRoT satellite
J. R. De Medeiros, C. E. Ferreira Lopes, I. C. Leao +13
To date, the CoRoT space mission has produced more than 124,471 light curves. Classifying these curves in terms of unambiguous variability behavior is mandatory for obtaining an un…
A catalog of rotational and radial velocities for evolved stars. IV. Metal-poor stars
J. R. De Medeiros, J. R. P. Silva, J. D. Jr. do Nascimento +4
The present paper describes the first results of an observational program intended to refine and extend the existing vsini measurements of metal-poor stars, with anemphasis on fiel…
On the link between rotation, chromospheric activity and Li abundance in subgiant stars
J. D Jr. do Nascimento, B. L. Canto Martins, C. H. F. Melo +2
The connection rotation-CaII emission flux-lithium abundance is analyzed for a sample of bona fide subgiant stars, with evolutionary status determined from HIPPARCOS trigonometric…
