Refined physical parameters for Chariklo's body and rings from stellar occultations observed between 2013 and 2020
B. E. Morgado, B. Sicardy, F. Braga-Ribas +78
The Centaur (10199) Chariklo has the first rings system discovered around a small object. It was first observed using stellar occultation in 2013. Stellar occultations allow the de…
HD 76920b pinned down: a detailed analysis of the most eccentric planetary system around an evolved star
C. Bergmann, M. I. Jones, J. Zhao +9
We present 63 new multi-site radial velocity measurements of the K1III giant HD 76920, which was recently reported to host the most eccentric planet known to orbit an evolved star.…
TARdYS: Design and Prototype of an Exoplanet Hunter for TAO using a R6 Echelle Grating
S. Rukdee, L. Vanzi, C. Schwab +7
One limitation in characterizing exoplanet candidates is the availability of infrared, high-resolution spectrographs. An important factor in the scarcity of high precision IR spect…
TOI-954 b and K2-329 b: Short-Period Saturn-Mass Planets that Test whether Irradiation Leads to Inflation
Lizhou Sha, Chelsea X. Huang, Avi Shporer +70
We report the discovery of two short-period Saturn-mass planets, one transiting the G subgiant TOI-954 (TIC 44792534, , ) observed in TESS sectors 4 and 5…
TOI-481 b & TOI-892 b: Two long period hot Jupiters from the Transiting Exoplanet Survey Satellite
Rafael Brahm, Louise D. Nielsen, Robert A. Wittenmyer +75
We present the discovery of two new 10-day period giant planets from the Transiting Exoplanet Survey Satellite () mission, whose masses were precisely determined using a wide…
Four Jovian planets around low-luminosity giant stars observed by the EXPRESS and PPPS
M. I. Jones, R. Wittenmyer, C. Aguilera-Gómez +12
We report the discovery of planetary companions orbiting four low-luminosity giant stars with M between 1.04 and 1.39 M. All four host stars have been independently…
MASCARA-4 b/bRing-1b - A retrograde hot Jupiter around the bright A3V star HD 85628
P. Dorval, G. J. J. Talens, G. P. P. L. Otten +25
In this paper, we aim to characterize a transiting planetary candidate in the southern skies found in the combined MASCARA and bRing data sets of HD 85628, an A3V star of V = 8.2 m…
HD 1397b: a transiting warm giant planet orbiting a V = 7.8 mag sub-giant star discovered by TESS
Rafael Brahm, Néstor Espinoza, Andrés Jordán +11
We report the discovery of a transiting planet first identified as a candidate in Sector 1 of the Transiting Exoplanet Survey Satellite (TESS), and then confirmed with precision ra…
K2-287b: an Eccentric Warm Saturn transiting a G-dwarf
Andrés Jordán, Rafael Brahm, Néstor Espinoza +23
We report the discovery of K2-287b, a Saturn mass planet orbiting a G-dwarf with a period of days. First uncovered as a candidate using K2 campaign 15 data, follow-u…
EPIC 201498078b: A low density Super Neptune on an eccentric orbit
Rafael Brahm, Nestor Espinoza, Markus Rabus +15
We report the discovery of EPIC 201498078b, which was first identified as a planetary candidate from Kepler K2 photometry of Campaign 14, and whose planetary nature and orbital par…
Precision stellar radial velocity measurements with FIDEOS at the ESO 1-m telescope of La Silla
L. Vanzi, A. Zapata, M. Flores +10
We present results from the commissioning and early science programs of FIDEOS, the new high-resolution echelle spectrograph developed at the Centre of Astro Engineering of Pontifi…
Beryllium detection in the very fast nova ASASSN-16kt (V407 Lupi)
L. Izzo, P. Molaro, P. Bonifacio +8
We present high-resolution spectroscopic observations of the fast nova ASASSN-16kt (V407 Lup). A close inspection of spectra obtained at early stages has revealed the presence of l…
A hot Saturn on an eccentric orbit around the giant star EPIC228754001
M. I. Jones, R. Brahm, N. Espinoza +10
Although the majority of radial velocity detected planets have been found orbiting solar-type stars, a fraction of them have been discovered around giant stars. These planetary sys…
