Analysis of combined radial velocities and activity of BD+20 1790: evidence supporting the existence of a planetary companion
(EDP Sciences, 2015)
Context. In a previous paper we reported a planetary companion to the young and very active K5Ve star BD+20 1790. We found
that this star has a high level of stellar activity (log R HK = −3.7) that manifests in a plethora ...
Signals embedded in the radial velocity noise Periodic variations in the τ Ceti velocities
(EDP Sciences, 2013)
Context. The abilities of radial velocity exoplanet surveys to detect the lowest-mass extra-solar planets are currently limited by a
combination of instrument precision, lack of data, and “jitter”. Jitter is a general ...
Radial Velocity Survey for Planets around Young stars (RVSPY) : Target characterisation and high-cadence survey
(EDP Sciences, 2022)
Context. The occurrence rate and period distribution of (giant) planets around young stars is still not as well constrained as for older main-sequence stars. This is mostly due to the intrinsic activity-related complications ...
Revisión de la biología reproductiva de los tiburones del género : Mustelus
Los tiburones son un grupo de animales importantes en los ecosistemas marinos, los cuales
actúan como reguladores y como bioindicadores, por lo que se encargan de mantener el
ecosistema en equilibrio y su ausencia traería ...
