Planetary-Mass Exosatellite Detected Around the Substellar Companion of a Star

Kevin Hoy, A. Zurlo, Pablo A. Peña R, Jana Köhler et autres

Despite more than 6000 exoplanets being discovered to date, no satellite orbiting an exoplanet, an exomoon, has ever been confidently detected. While there are some candidates, they lack clear and convincing confirmation and remain controversial. Beyond the innate value of discovering new …

A four-planet system orbiting the old thick disk star TOI-1203

D. Gandolfi, A. Alnajjarine, L. M. Serrano, J.A. Egger et autres

TOI-1203 is a bright (V,=,8.6) G3,V star known to host a transiting warm sub-Neptune on a 25.5-day orbit. Here we report on an intensive high-precision radial velocity and photometric follow-up campaign carried out with the spectrograph and the ̧heops space telescope. We …

Testing the bloated star hypothesis in the massive young stellar object IRAS 19520+2759 through optical and infrared variability

R. Pandey, Aina Palau, Javier Serna, R. Kuiper et autres

Abstract Using optical time series with Telescopi Joan Oró (TJO), Gaia, TESS, and NEOWISE archival data, we performed a variability study on the candidate bloated massive young stellar object (MYSO) IRAS 19520+2759. This is the first time that a bloated star candidate …

TOI-544 b: a potential water-world inside the radius valley in a two-planet system

H. L. M. Osborne, Elisa Goffo, D. Gandolfi, G. Nowak et autres

ABSTRACT We report on the precise radial velocity follow-up of TOI-544 (HD 290498), a bright K star (V = 10.8), which hosts a small transiting planet recently discovered by the Transiting Exoplanet Survey Satellite (TESS). We collected 122 high-resolution High Accuracy Radial …

TOI-544 b: a potential water-world inside the radius valley in a two-planet system

H. L. M. Osborne, Vincent Van Eylen, Elisa Goffo, D. Gandolfi et autres

We report on the precise radial velocity follow-up of TOI-544 (HD 290498), a bright K star (V=10.8), which hosts a small transiting planet recently discovered by the Transiting Exoplanet Survey Satellite (TESS). We collected 122 high-resolution HARPS and HARPS-N spectra to spectroscopically …

Company for the Ultra-high Density, Ultra-short Period Sub-Earth GJ 367 b: Discovery of Two Additional Low-mass Planets at 11.5 and 34 Days*

Elisa Goffo, D. Gandolfi, J. A. Egger, Alexander J. Mustill et autres

Abstract GJ 367 is a bright (V ≈ 10.2) M1 V star that has been recently found to host a transiting ultra-short period sub-Earth on a 7.7 hr orbit. With the aim of improving the planetary mass and radius and unveiling the …

Retrieval of the dayside atmosphere of WASP-43b with CRIRES +

F. Lesjak, L. Nortmann, F. Yan, D. Cont et autres

Accurately estimating the C/O ratio of hot Jupiter atmospheres is a promising pathway towards understanding planet formation and migration, as well as the formation of clouds and the overall atmospheric composition. The atmosphere of the hot Jupiter WASP-43b has been extensively analysed …
