Precision measurement of a brown dwarf mass in a binary system in the microlensing event OGLE-2019-BLG-0033/MOA-2019-BLG-035
A. Herald, A. Udalski, V. Bozza +89
Context. Brown dwarfs are poorly understood transition objects between stars and planets, with several competing mechanisms having been proposed for their formation. Mass measureme…
Multi-instrumental view of magnetic fields and activity of Eridani with SPIRou, NARVAL, and TESS
P. Petit, C. P. Folsom, J. -F. Donati +6
We report on observations of the active K2 dwarf Eridani based on contemporaneous SPIRou, NARVAL, and TESS data obtained over two months in late 2018, when the activity of the…
Microlensing path parametrization for Earth-like Exoplanet detection around solar mass stars
L. de Almeida, J. -D. do Nascimento
We propose a new parametrization of the impact parameter u0 and impact angle α for microlensing systems composed by an Earth-like Exoplanet around a Solar mass Star at 1 AU. We pre…
iota Horologii is unlikely to be an evaporated Hyades star
I. Ramirez, D. Yong, E. Gutierrez +3
We present a high-precision chemical analysis of iota Horologii, a planet-host field star thought to have formed in the Hyades. Elements with atomic number 6<=Z<=30 have abundances…
The future of the Sun: an evolved solar twin revealed by CoRoT
J. -D. do Nascimento, Y. Takeda, J. Melendez +3
The question of whether the Sun is peculiar within the class of solar-type stars has been the subject of active investigation over the past three decades. Although several solar tw…
Rotational periods and evolutionary models for subgiant stars observed by CoRoT
J. -D. Jr. do Nascimento, J. S. da Costa, M. Castro
We present rotation period measurements for subgiants observed by CoRoT. Interpreting the modulation of stellar light that is caused by star-spots on the time scale of the rotation…
