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…
ACTIN: A tool to calculate stellar activity indices
J. Gomes da Silva, P. Figueira, N. C. Santos +1
Magnetic activity in the atmospheres of stars produces a number of spectroscopic signatures that are visible in the shape and strength of spectral lines. These signatures can be us…
Telluric correction in the near-infrared: Standard star or synthetic transmission?
S. Ulmer-Moll, P. Figueira, J. J. Neal +2
Context. The atmospheric absorption of the Earth is an important limiting factor for ground-based spectroscopic observations and the near-infrared and infrared regions are the most…
SWEET-Cat updated. New homogenous spectroscopic parameters
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +14
Context: Exoplanets have now been proven to be very common. The number of its detections continues to grow following the development of better instruments and missions. One key ste…
K2-263b: A 50-day period sub-Neptune with a mass measurement using HARPS-N
A. Mortier, A. S. Bonomo, V. M. Rajpaul +32
This paper reports on the validation and mass measurement of K2-263b, a sub-Neptune orbiting a quiet G9V star. Using K2 data from campaigns C5 and C16, we find this planet to have…
Activity induced variation in spin-orbit angles as derived from Rossiter-McLaughlin measurements
M. Oshagh, A. H. M. J. Triaud, A. Burdanov +17
One of the most powerful methods used to estimate sky-projected spin-orbit angles of exoplanetary systems is through a spectroscopic transit observation known as the Rossiter-McLau…
