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

Kevin Hoy, Alice Zurlo, Pablo A. Peña R. +10

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, the…

Mass determination of the ultra-short-period planet LHS 3844 b. First K-band radial velocity measurements with CRIRES+

E. Nagel, J. Köhler, M. Zechmeister +21

We present the first planet mass measurement obtained with CRIRES+ radial velocity (RV) observations using the K-band gas cell. Our target, LHS 3844 b (TOI-136), is a transiting su…

Mass determination of the three long-period Neptune- and sub-Neptune-sized planets transiting TOI-282

A. Barone, F. Rodler, D. Gandolfi +16

TOI-282 is a bright (V=9.38) F8 main-sequence star known to host three transiting long-period (=22.9 d, =56.0 d, and =84.3 d) small ( 2-4 ) p…

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

D. Gandolfi, A. Alnajjarine, L. M. Serrano +120

TOI-1203 is a bright (V=8.6) G3 V star known to host a transiting warm sub-Neptune on a 25.5 d orbit. Here we report on an intensive high-precision radial velocity and photometric…

viper: High-precision radial velocities from the optical to the infrared (Reaching 3 m/s in the K band of CRIRES+ with telluric modelling)

J. Köhler, M. Zechmeister, A. Hatzes +18

In recent years, a number of new instruments and data reduction pipelines have been developed to obtain high-precision radial velocities (RVs). In particular in the optical, consid…

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

Rakesh Pandey, Aina Palau, Javier Serna +8

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 obj…
