Spinning out of focus: The challenge of rotational line broadening in exoplanet reflection spectroscopy
T. O. Winterhalder, K. Molaverdikhani, D. Cont +17
Detecting light reflected off the dayside of an exoplanet in high-resolution spectroscopic data has proved to be a notoriously difficult endeavour. Despite several attempts, the fa…
Characterization of two new transiting sub-Neptunes and a terrestrial planet around M-dwarf hosts
E. Poultourtzidis, G. Lacedelli, E. Pallé +49
We report the confirmation of three transiting exoplanets orbiting TOI-1243 (LSPM~J0902+7138), TOI-4529 (G~2--21), and TOI-5388 (Wolf~346) that were initially detected by TESS thro…
The CARMENES search for exoplanets around M dwarfs : Understanding the wavelength dependence of radial velocity measurements
S. V. Jeffers, J. R. Barnes, P. Schöfer +22
Context. Current exoplanet surveys are focused on detecting small exoplanets orbiting in the liquid-water habitable zones of their host stars. Despite the recent significant advanc…
A planetary system with a sub-Neptune planet in the habitable zone of TOI-2093
J. Sanz-Forcada, E. González-Ãlvarez, M. R. Zapatero Osorio +33
Aims. We aim to confirm and measure the mass of the transiting planet candidate around the K5V star TOI-2093, previously announced by the Transiting Exoplanet Survey Satellite (TES…
The CARMENES search for exoplanets around M dwarfs. Cluster analysis of signals from spectral activity indicators to search for shared periods
J. Kemmer, M. Lafarga, B. Fuhrmeister +17
A multitude of spectral activity indicators are routinely computed nowadays from the spectra generated as part of planet-hunting radial velocity surveys. Searching for shared perio…
