Characterization of the known T type dwarfs towards the Sigma Orionis cluster
K. Peña Ramírez, M. R. Zapatero Osorio, V. J. S. Béjar
(Abridged) A total of three T type candidates (SOri70, SOri73, and SOriJ0538-0213) lying in the line of sight towards Sigma Orionis were characterized by means of near-infrared pho…
Spectroscopic follow-up of L- and T-type proper-motion member candidates in the Pleiades
M. R. Zapatero Osorio, V. J. S. Béjar, E. L. Martín +9
(Abridged) We report on the near-infrared low-resolution spectroscopy and red optical (Z-band) photometry of seven proper-motion, very low-mass substellar member candidates of the…
ExELS: an exoplanet legacy science proposal for the ESA Euclid mission. II. Hot exoplanets and sub-stellar systems
I. McDonald, E. Kerins, M. Penny +11
The Exoplanet Euclid Legacy Survey (ExELS) proposes to determine the frequency of cold exoplanets down to Earth mass from host separations of ~1 AU out to the free-floating regime…
Search for free-floating planetary-mass objects in the Pleiades
M. R. Zapatero Osorio, M. C. Gálvez Ortiz, G. Bihain +8
(Abridged) We aim at identifying the least massive population of the solar metallicity, young (120 Myr), nearby (133.5 pc) Pleiades star cluster with the ultimate goal of understan…
Trigonometric parallaxes of young field L dwarfs
M. R. Zapatero Osorio, V. J. S. Béjar, P. Miles-Páez +3
(Abridged) We aim to determine the trigonometric parallaxes and proper motions of a sample of ten field L0-L5 dwarfs with spectroscopic evidence for low-gravity atmospheres. We obt…
2MASS J154043.42-510135.7: a new addition to the 5 pc population
A. Perez-Garrido, N. Lodieu, V. J. S. Bejar +4
The aim of the project is to find the stars nearest to the Sun and to contribute to the completion of the stellar and substellar census of the solar neighbourhood. We identified a…
Simultaneous optical and near-infrared linear spectropolarimetry of the earthshine
P. A. Miles-Páez, E. Pallé, M. R. Zapatero Osorio
Aims: We aim to extend our current observational understanding of the integrated planet Earth spectropolarimetry from the optical to the near-infrared wavelengths. Major biomarkers…
ESPRESSO: The next European exoplanet hunter
F. Pepe, P. Molaro, S. Cristiani +55
The acronym ESPRESSO stems for Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations; this instrument will be the next VLT high resolution spectrograph. T…
The GTC exoplanet transit spectroscopy survey I: OSIRIS transmission spectroscopy of the short period planet WASP-43b
F. Murgas, E. Palle, M. R. Zapatero Osorio +3
We used GTC instrument OSIRIS to obtain long-slit spectra in the optical range (520-1040 nm) of the planetary host star WASP-43 (and a reference star) during a full primary transit…
