Montes Gutiérrez, David ; González Peinado, R. ; Tabernero, H. M. ; Caballero, J. A. ; Gómez Marfil, Emilio ; Alonso Floriano, F. J. ; Cortés Contreras, Miriam ; González Hernández, J. I. ; Klutsch, A. ; Moreno Jodar, C. | Oxford Univ Press | 2018-09We investigated almost 500 stars distributed among 193 binary or multiple systems made of late-E, G-, or earl y-K-primaries and late-K- or M-dwarf companion candidates, For all of them, we compiled or measured coordinates, J-band magnitudes, spe[...]texto impreso
Alonso Floriano, F. J. ; Morales, J. C. ; Caballero, J. A. ; Montes Gutiérrez, David ; Klutsch, A. ; Mundt, R. ; Cortés Contreras, Miriam ; Ribas, I. ; Reiners, A. ; Amado, P. J. ; Quirrenbach, A. ; Jeffers, S. V. | EDP Sciencies | 2015-05Context. CARMENES is a stabilised, high-resolution, double-channel spectrograph at the 3.5m Calar Alto telescope. It is optimally designed for radial-velocity surveys of M dwarfs with potentially habitable Earth-mass planets. Aims. We prepare a [...]texto impreso
Ivanov, M. V. ; Megías, G. D. ; González Jiménez, R. ; Moreno, O. ; Bárbaro, M. B. ; Caballero, J. A. ; Donnelly, T. W. ; Antonov, A. N. ; Moya de Guerra, Elvira ; Udías Moinelo, José Manuel | Amer Inst Physics | 2016SuperScaling model (SuSA) predictions to neutrino-induced charged-current pi(+) production in the Delta-resonance region are explored under MiniBooNE experimental conditions. The SuSA charged-current pi(+) results are in good agreement with data[...]texto impreso
Ultra-hot Jupiters (UHJs) are highly irradiated giant exoplanets with extremely high day-side temperatures, which lead to thermal dissociation of most of the molecular species. It is expected that the neutral hydrogen atom is one of the main spe[...]texto impreso
Megías, G. D. ; Ivanov, M. V. ; González Jiménez, R. ; Caballero, J. A. ; Bárbaro, M. B. ; Donnelly, T. W. ; Udías Moinelo, José Manuel | Amer Physical Soc | 2015-02-11texto impreso
Caballero, J. A. ; Cornide Castro-Piñeiro, Manuel ; Castro Rubio, Elisa de | Wiley-VCH Verlag GmbH | 2010-03We look for high-amplitude variable young stars in the open clusters and associations of the Orion Belt. We use public data from the ASAS-3 Photometric V -band Catalogue of the All Sky Automated Survey, infrared photometry from the 2MASS and IRA[...]texto impreso
Sanz Forcada, J. ; Caballero, J. A. ; Labarga Ávalos, F. ; Montes Gutiérrez, David | EDP Sciencies | 2019-09Context. Recently, the He I triplet at 10 830 Å was rediscovered as an excellent probe of the extended and possibly evaporating atmospheres of close-in transiting planets. This has already resulted in detections of this triplet in the atmosphere[...]texto impreso
Ultra-hot Jupiters are emerging as a new class of exoplanets. Studying their chemical compositions and temperature structures will improve our understanding of their mass loss rate as well as their formation and evolution. We present the detecti[...]texto impreso
Caballero, J. A. ; Valdivielso, L. ; Martín, E. L. ; Montes Gutiérrez, David ; Pascual, S. ; Pérez González, Pablo Guillermo | EDP Sciencies | 2008-11Aims. We study in detail nine sources in the direction of the young ? Orionis cluster, which is considered to be a unique site for studying stellar and substellar formation. The nine sources were selected because of their peculiar properties, su[...]texto impreso
Context. HD 209458 b is an exoplanet with an upper atmosphere undergoing blow-off escape that has mainly been studied using measurements of the Ly? absorption. Recently, high-resolution measurements of absorption in the He I triplet line at 10 8[...]texto impreso

A. ; González Jiménez, A. ; Moya de Guerra, Elvira ; Udías Moinelo, José Manuel | Amer Physical Soc | 2015-03-12Neutral current quasielastic ( anti) neutrino scattering cross sections on a C-12 target are analyzed using a realistic spectral function S( p, E) that gives a scaling function in accordance with the ( e, e') scattering data. The spectral functi[...]texto impreso
Ivanov, M. V. ; Antonov, A. N. ; Megías, G. D. ; González-Jiménez, R. ; Bárbaro, M. B. ; Caballero, J. A. ; Donnelly, T. W. ; Udías Moinelo, José Manuel | IOP publishing ltd | 2018We compare the characteristics of the charged-current quasielastic (anti)neutrino scattering obtained in two different nuclear models, the phenomenological SuperScaling Approximation and the model using a realistic spectral function S(p, epsilon[...]texto impreso

Caballero, J. A. ; Cortés Contreras, Miriam ; Montes Gutiérrez, David | EDP SCIENCES S A | 2019-08-06We report the detection of a transiting Earth-size planet around GJ 357, a nearby M2.5 V star, using data from the Transiting Exoplanet Survey Satellite (TESS). GJ 357 b (TOI-562.01) is a transiting, hot, Earth-sized planet (T_(eq) = 525 ± 11 K)[...]texto impreso
Alonso Floriano, F. J. ; Caballero, J. A. ; Cortés Contreras, Miriam ; Solano, E. ; Montes Gutiérrez, David | EDP Sciencies | 2015-11Aims. We look for common proper motion companions to stars of the nearby young ??Pictoris moving group. Methods. First, we compiled a list of 185 ??Pictoris members and candidate members from 35 representative works. Next, we used the Aladin and[...]
