The SOPHIE search for northern extrasolar planets. XIV. A temperate ( K) super-earth around the nearby star Gliese 411
R. F. Díaz, X. Delfosse, M. J. Hobson +33
Periodic radial velocity variations in the nearby M-dwarf star Gl411 are reported, based on measurements with the SOPHIE spectrograph. Current data do not allow us to distinguish b…
Hot, rocky and warm, puffy super-Earths orbiting TOI-402 (HD 15337)
X. Dumusque, O. Turner, C. Dorn +30
TESS is revolutionising the search for planets orbiting bright and nearby stars. In sectors 3 and 4, TESS observed TOI-402 (TIC-120896927), a bright V=9.1 K1 dwarf also known as HD…
The SOPHIE search for northern extrasolar planets XV. A Warm Neptune around the M-dwarf Gl378
M. J. Hobson, X. Delfosse, N. Astudillo-Defru +31
We present the detection of a Warm Neptune orbiting the M-dwarf Gl378, using radial velocity measurements obtained with the SOPHIE spectrograph at the Observatoire de Haute-Provenc…
K2-291 b: A rocky super-Earth in a 2.2 day orbit
Molly R. Kosiarek, Sarah Blunt, Mercedes Lopez-Morales +43
K2-291 (EPIC 247418783) is a solar-type star with a radius of R_star = 0.899 0.034 R_sun and mass of M_star=0.934 0.038 M_sun. From K2 C13 data, we found one super-Eart…
HARPS-N Solar Radial-Velocity Variations Are Dominated By Large, Bright Magnetic Regions
T. W. Milbourne, R. D. Haywood, D. F. Phillips +37
State of the art radial-velocity (RV) exoplanet searches are currently limited by RV signals arising from stellar magnetic activity. We analyze solar observations acquired over a 3…
HARPS-N radial velocities confirm the low densities of the Kepler-9 planets
L. Borsato, L. Malavolta, G. Piotto +20
We investigated the discrepancy between planetary mass determination using the transit timing variations (TTVs) and radial velocities (RVs), by analysing the multi-planet system Ke…
