CORALIE radial-velocity search for companions around evolved stars (CASCADES) IV: New planetary systems around HD 87816, HD 94890, and HD 102888 and an update on HD 121056
E. Fontanet, S. Udry, D. Ségransan +25
With around 200 detections of exoplanets around giant stars to date, our knowledge of the population of exoplanets orbiting evolved hosts more massive than the Sun remains limited.…
TOI-858 B b: A hot Jupiter on a polar orbit in a loose binary
J. Hagelberg, L. D. Nielsen, O. Attia +30
We report the discovery of a hot Jupiter on a 3.28-day orbit around a 1.08 M G0 star that is the secondary component in a loose binary system. Based on follow-up radial vel…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) VIII. Nondetection of sodium in the atmosphere of the aligned planet KELT-10b
M. Steiner, O. Attia, D. Ehrenreich +17
We searched for potential atmospheric species in KELT-10b, focusing on sodium doublet lines (Na i; 589 nm) and the Balmer alpha line (H ; 656 nm) in the transmission spectrum. F…
Coralie radial-velocity search for companions around evolved stars (CASCADES) III. A new Jupiter host-star: in-depth analysis of HD 29399 using TESS data
C. Pezzotti, G. Ottoni, G. Buldgen +11
Context. Increasing the number of detected exoplanets is far from anecdotal, especially for long-period planets that require a long duration of observation. More detections imply a…
Coralie radial velocity search for companions around evolved stars (CASCADES) II. Seismic masses for three red giants orbited by long-period massive planets
G. Buldgen, G. Ottoni, C. Pezzotti +10
The advent of asteroseismology as the golden path to precisely characterize single stars naturally led to synergies with the field of exoplanetology. Today, the precise determinati…
CORALIE radial-velocity search for companions around evolved stars (CASCADES). I. Sample definition and first results: Three new planets orbiting giant stars
G. Ottoni, S. Udry, D. Ségransan +11
Context. Following the first discovery of a planet orbiting a giant star in 2002, we started the CORALIE radial-velocity search for companions around evolved stars (CASCADES). We p…
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…
Lithium in red giant stars: Constraining non-standard mixing with large surveys in the Gaia era
C. Charbonnel, N. Lagarde, G. Jasniewicz +7
Lithium is extensively known to be a good tracer of non-standard mixing processes occurring in stellar interiors. We present the results of a new large Lithium survey in red giant…
The CORALIE survey for southern extrasolar planets XVIII. Three new massive planets and two low mass brown dwarfs at separation larger than 5 AU
E. L. Rickman, D. Ségransan, M. Marmier +36
Context. Since 1998, a planet-search around main sequence stars within 50~pc in the southern hemisphere has been carried out with the CORALIE spectrograph at La Silla Observatory.…
Near-resonance in a system of sub-Neptunes from TESS
Samuel N. Quinn, Juliette C. Becker, Joseph E. Rodriguez +78
We report the Transiting Exoplanet Survey Satellite () detection of a multi-planet system orbiting the K0 dwarf TOI 125. We find evidence for up to five planets, wit…
A Jovian planet in an eccentric 11.5 day orbit around HD1397 discovered by TESS
L. D. Nielsen, F. Bouchy, O. Turner +36
The Transiting Exoplanet Survey Satellite TESS has begun a new age of exoplanet discoveries around bright host stars. We present the discovery of HD 1397b (TOI-120.01), a giant pla…
TESS Discovery of an ultra-short-period planet around the nearby M dwarf LHS 3844
Roland Vanderspek, Chelsea X. Huang, Andrew Vanderburg +45
Data from the newly-commissioned \textit{Transiting Exoplanet Survey Satellite} (TESS) has revealed a "hot Earth" around LHS 3844, an M dwarf located 15 pc away. The planet has a r…
