The K2-OjOS Project: New and revisited planets and candidates in K2 campaigns 5, 16, & 18
A. Castro-González, E. Díez Alonso, J. Menéndez Blanco +28
We present the first results of K2-OjOS, a collaborative project between professional and amateur astronomers primarily aimed to detect, characterize, and validate new extrasolar p…
Planetary candidates transiting cool dwarf stars from Campaigns 12 to 15 of K2
A. Castro González, E. Díez Alonso, J. Menéndez Blanco +15
We analyzed the photometry of 20038 cool stars from campaigns 12, 13, 14 and 15 of the K2 mission in order to detect, characterize and validate new planetary candidates transiting…
Precise mass and radius of a transiting super-Earth planet orbiting the M dwarf TOI-1235: a planet in the radius gap?
P. Bluhm, R. Luque, N. Espinoza +78
We report the confirmation of a transiting planet around the bright, inactive M0.5 V star TOI-1235 (TYC 4384-1735-1, V = 11.5 mag), whose transit signal was detected in the photome…
QSOs sigposting cluster size halos as gravitational lenses: halo mass, projected mass density profile and concentration at
L. Bonavera, J. González-Nuevo, S. L. Suárez Gómez +6
Magnification bias is a gravitational lensing effect that is normally overlooked because it is considered sub-optimal in comparison with the lensing shear. Thanks to the demonstrat…
CARMENES input catalogue of M dwarfs IV. New rotation periods from photometric time series
E. Diez Alonso, J. A. Caballero, D. Montes +21
Aims. The main goal of this work is to measure rotation periods of the M-type dwarf stars being observed by the CARMENES exoplanet survey to help distinguish radial-velocity signal…
Two planetary systems with transiting Earth-size and super-Earth planets orbiting late-type dwarf stars
E. Diez Alonso, J. I. Gonzalez Hernandez, S. L. Suarez Gomez +9
We present two new planetary systems found around cool dwarf stars with data from the K2 mission. The first system was found in K2-239 (EPIC 248545986), char- acterized in this wor…
