Silicon in the dayside atmospheres of two ultra-hot Jupiters

D. Cont, F. Yan, A. Reiners +22

Atmospheres of highly irradiated gas giant planets host a large variety of atomic and ionic species. Here we observe the thermal emission spectra of the two ultra-hot Jupiters WASP…

A multi-planetary system orbiting the early-M dwarf TOI-1238

E. González-Álvarez, M. R. Zapatero Osorio, J. Sanz-Forcada +53

Two transiting planet candidates with super-Earth radii around the nearby K7--M0 dwarf star TOI-1238 were announced by TESS. We aim to validate their planetary nature using precise…

Rapid contraction of giant planets orbiting the 20 million-years old star V1298 Tau

A. Suárez Mascareño, M. Damasso, N. Lodieu +41

Current theories of planetary evolution predict that infant giant planets have large radii and very low densities before they slowly contract to reach their final size after about…

The CARMENES search for exoplanets around M dwarfs. Diagnostic capabilities of strong K I lines for photosphere and chromosphere

B. Fuhrmeister, S. Czesla, E. Nagel +20

There are several strong K I lines found in the spectra of M dwarfs, among them the doublet near 7700 AA and another doublet near 12 500 AA. We study these optical and near-infrare…

H and He I absorption in HAT-P-32 b observed with CARMENES -- Detection of Roche lobe overflow and mass loss

S. Czesla, M. Lampón, J. Sanz-Forcada +22

We analyze two high-resolution spectral transit time series of the hot Jupiter HAT-P-32 b obtained with the CARMENES spectrograph. Our new XMM-Newton X-ray observations of the syst…

Retrieving the transmission spectrum of HD 209458b using CHOCOLATE: A new chromatic Doppler tomography technique

E. Esparza-Borges, M. Oshagh, N. Casasayas-Barris +29

Multiband photometric transit observations or low-resolution spectroscopy (spectro-photometry) are normally used to retrieve the broadband transmission spectra of transiting exopla…

GTC/CanariCam deep mid-infrared imaging survey of northern stars within 5 pc

Bartosz Gauza, Víctor J. S. Béjar, Rafael Rebolo +7

In this work we present the results of a direct imaging survey for brown dwarf companions around the nearest stars at the mid-infrared 10 micron range (=8.7m, =1.1…

TOI-1201 b: A mini-Neptune transiting a bright and moderately young M dwarf

D. Kossakowski, J. Kemmer, P. Bluhm +62

We present the discovery of a transiting mini-Neptune around TOI-1201, a relatively bright and moderately young early M dwarf ( 9.5 mag, 600-800 Myr) in an equal-m…

Probing the atmosphere of WASP-69 b with low- and high-resolution transmission spectroscopy

S. Khalafinejad, K. Molaverdikhani, J. Blecic +31

Consideration of both low- and high-resolution transmission spectroscopy is key for obtaining a comprehensive picture of exoplanet atmospheres. In studies of transmission spectra,…

The CARMENES search for exoplanets around M dwarfs, No evidence for a super-Earth in a 2-day orbit around GJ 1151

M. Perger, I. Ribas, G. Anglada-Escudé +20

The interaction between Earth-like exoplanets and the magnetic field of low-mass host stars are considered to produce weak emission signals at radio frequencies. A study using LOFA…
