Revisiting the atmosphere of HAT-P-70b with CARMENES high-resolution transmission spectroscopy
Tianjun Gan, Jaume Orell-Miquel, Fei Yan +19
Owing to hot and inflated envelopes that facilitate atmospheric studies, ultra-hot Jupiters (UHJs) have attracted much attention. Significant progress has been achieved, from enlar…
Tighter constraints on the atmosphere of GJ 436 b from combined high-resolution CARMENES and CRIRES observations
A. Peláez-Torres, A. Sánchez-López, L. Nortmann +23
We aim to study the atmospheric properties of the warm Neptune GJ 436 b by combining a set of five transit events observed with the CARMENES spectrograph with one transit from CRIR…
Upper limits on atmospheric abundances of KELT-11b and WASP-69b from a retrieval approach
F. Lesjak, L. Nortmann, D. Cont +18
WASP-69b and KELT-11b are two low-density hot Jupiters, which are expected to show strong atmospheric features in their transmission spectra. Such features offer valuable insights…
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…
Improving radial velocity precision with CARMENES-PLUS:An upgrade of the near-infrared spectrograph cooling system
R. Varas, R. Calvo-Ortega, P. J. Amado +25
CARMENES is a dual-channel high-resolution spectrograph at the 3.5 m Calar Alto telescope designed to detect low-mass planets around late-type dwarfs by measuring their radial velo…
Discovery of a transiting hot water-world candidate orbiting Ross 176 with TESS and CARMENES
S. Geraldía-González, J. Orell-Miquel, E. Pallé +30
The case of Ross 176 is a late K-type star that hosts a promising water-world candidate planet. The star has a radius of =0.5690.020 and a mass of …
The CARMENES search for exoplanets around M dwarfs. Revisiting the GJ 317, GJ 463, and GJ 3512 systems and two newly discovered planets orbiting GJ 9773 and GJ 508.2
J. C. Morales, I. Ribas, S. Reffert +33
Surveys for exoplanets indicate that the occurrence rate of gas giant planets orbiting late-type stars in orbits with periods shorter than 1000 days is lower than in the case of Su…
The mass of the exo-Venus Gliese 12 b, as revealed by HARPS-N, ESPRESSO, and CARMENES
Daisy A. Turner, Yoshi Nike Emilia Eschen, Felipe Murgas +60
Small temperate planets are prime targets for exoplanet studies due to their possible similarities with the rocky planets in the Solar System. M dwarfs are promising hosts since th…
Retrieving day- and nightside atmospheric properties of the ultra-hot Jupiter TOI-2109b. Detection of Fe and CO emission lines and evidence for inefficient heat transport
D. Cont, L. Nortmann, F. Lesjak +32
The ultra-hot Jupiter (UHJ) TOI-2109b marks the lower edge of the equilibrium temperature gap between 3500 K and 4500 K, an unexplored thermal regime that separates KELT-9b, the ho…
The CARMENES search for exoplanets around M dwarfs. Occurrence rates of Earth-like planets around very low-mass stars
A. Kaminski, S. Sabotta, J. Kemmer +24
Aims: Previous estimates of planet occurrence rates in the CARMENES survey indicated increased numbers of planets on short orbits for M dwarfs with masses below 0.34\,M. He…
Coronal and chromospheric activity of Teegarden's star
B. Fuhrmeister, J. H. M. M. Schmitt, A. Reienrs +10
Teegarden's star is a late-type M-dwarf planet host, typically showing only rather low levels of activity. In this paper we present an extensive characterisation of this activity a…
CARMENES as an Instrument for Exoplanet Research
José A. Caballero, Walter Seifert, Andreas Quirrenbach +3
CARMENES stands for Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Échelle Spectrographs. CARMENES took six years from a concept to th…
Connection between planetary He I 10830 Å absorption and extreme-ultraviolet emission of planet-host stars
J. Sanz-Forcada, M. López-Puertas, M. Lampón +13
Context. The detection of the He I 10830 A triplet in exoplanet atmospheres has opened a new window for probing planetary properties, including atmospheric escape. Unlike Lyman alp…
