N. Casasayas-Barris,Enric Palle,Fei Yan,Gang Chen,S. Kohl,M. Stangret,Hannu Parviainen,Christiane Helling,N. Watanabe,S. Czesla,Akihiko Fukui,Pilar Montañés-Rodríguez,Erick Nagel,Norio Narita,Lisa Nortmann,Grzegorz Nowak,J.H.M.M. Schmit,M. R. Zapatero Osorio +17 more
TL;DR: In this article, the authors studied the atmosphere of one of these particular hot planets, MASCARA-2b/KELT-20b, using four transit observations with high resolution spectroscopy facilities.
Journal ArticleDOI

Zapatero Osorio,Mathias Zechmeister +37 more
TL;DR: In this article, the authors present three transit observations of HD 189733 b obtained with the high-resolution spectrograph CARMENES at Calar Alto, and show that stellar activity related pseudo-signals interfere with the planetary atmospheric absorption signal.
Journal ArticleDOI

Montes,Enric Palle,J. H. M. M. Schmitt,M. R. Zapatero Osorio +29 more
TL;DR: In this paper, the authors measured the helium excess absorption from HD 209458 b and assessed the extended atmosphere of the planet and possible evaporation using CARMENES at the 3.5 m Calar Alto telescope.
Journal ArticleDOI

R. Zapatero Osorio,Mathias Zechmeister +26 more
TL;DR: In this paper, the authors report their observations of three transits of a Neptune-size planet with CARMENES in search of \het\ absorption, and they find that the mass loss rate, \mlr, is confined to a range of 3\,$\times\,10^{10}$\,\gs\ for $T$ = 6000\,K to 10\,€\times \,10€ 10€,€ 0.14$ at this wavelength, whereas a statistically valid detection can only be claimed for the night with higher S/

TL;DR: In this article, the authors presented the discovery and characterisation of two transiting planets observed by the Transiting Exoplanet Survey Satellite (TESS) orbiting the nearby (d ~ 22 pc), bright (J ~ 9 mag) M3.5 dwarf LTT 3780 (TOI-732) via ground-based photometry and determined their masses using precise radial velocities measured with the CARMENES spectrograph.
