A super-Earth orbiting the nearby M-dwarf GJ 536
A. Suárez Mascareño, J. I. González Hernández, R. Rebolo +13
We report the discovery of a super-Earth orbiting the star GJ 536 based on the analysis of the radial-velocity time series from the HARPS and HARPS-N spectrographs. GJ 536 b is a p…
The HADES RV Programme with HARPS-N@TNG IV. Time resolved analysis of the Ca ii H&K and Hα chromospheric emission of low-activity early-type M dwarfs
G. Scandariato, J. Maldonado L. Affer, K. Biazzo +22
M dwarfs are prime targets for planet search programs, particularly of those focused on the detection and characterization of rocky planets in the habitable zone. Understanding the…
Extremely fast orbital decay of the black hole X-ray binary Nova Muscae 1991
J. I. González Hernández, L. Suárez-Andrés, R. Rebolo +1
We present new medium-resolution spectroscopic observations of the black hole X-ray binary Nova Muscae 1991 taken with X-Shooter spectrograph installed at the 8.2m-VLT telescope. T…
Magnetic Cycles and Rotation Periods of Late Type Stars from photometric time series
A. Suárez Mascareño, R. Rebolo, J. I. González Hernández
We investigate the photometric modulation induced by magnetic activity cycles and study the relationship between rotation period and activity cycle(s) in late-type (FGKM) stars. We…
Follow-up observations of extremely metal-poor stars identified from SDSS
D. S. Aguado, C. Allende Prieto, J. I. González Hernández +5
The most metal-poor stars in the Milky Way witnessed the early phases of formation of the Galaxy, and have chemical compositions that are close to the pristine mixture from Big Ban…
