HD219666b: A hot-Neptune from TESS Sector 1
M. Esposito, D. J. Armstrong, D. Gandolfi +73
We report on the confirmation and mass determination of a transiting planet orbiting the old and inactive G7 dwarf star HD219666 (Mstar = 0.92 +/- 0.03 MSun, Rstar = 1.03 +/- 0.03…
The asteroseismic potential of CHEOPS
A. Moya, S. Barceló Forteza, A. Bonfanti +3
Asteroseismology has been impressively boosted during the last decade mainly thanks to space missions such as Kepler/K2 and CoRoT. This has a large impact, in particular, in exopla…
The Rotational Evolution of Young, Binary M Dwarfs
John Stauffer, Luisa Rebull, Ann Marie Cody +5
We have analysed K2 light curves for more than 3,000 low mass stars in the 8 Myr old Upper Sco association, the 125 Myr age Pleiades open cluster and the 700 Myr…
K2-265 b: A Transiting Rocky Super-Earth
K. W. F. Lam, A. Santerne, S. G. Sousa +34
We report the discovery of the super-Earth K2-265 b detected with K2 photometry. The planet orbits a bright (V_mag = 11.1) star of spectral type G8V with a period of 2.37 days. We…
The TROY project: II. Multi-technique constraints on exotrojans in nine planetary systems
J. Lillo-Box, A. Leleu, H. Parviainen +10
Co-orbital bodies are the byproduct of planet formation and evolution, as we know from the Solar System. Although planet-size co-orbitals do not exists in our planetary system, dyn…
Gaia Data Release 2. Summary of the contents and survey properties
Gaia Collaboration, A. G. A. Brown, A. Vallenari +4
We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources…
