Measuring precise radial velocities on individual spectral lines. IV. Stellar activity correlation with line formation temperature
K. Al Moulla, X. Dumusque, M. Cretignier
Context. Radial velocities (RVs) of stars contain both the Doppler reflex motion of potential planetary companions and the drowning and sometimes imitating effect of stellar activi…
The magnetically quiet solar surface dominates HARPS-N solar RVs during low activity
Ben S. Lakeland, Tim Naylor, Raphaëlle Haywood +15
Using images from the Helioseismic and Magnetic Imager aboard the \textit{Solar Dynamics Observatory} (SDO/HMI), we extract the radial-velocity (RV) signal arising from the suppres…
The SOPHIE search for northern extrasolar planets-XIX. A system including a cold sub-Neptune potentially transiting a V = 6.5 star HD88986
N. Heidari, I. Boisse, N. C. Hara +51
Transiting planets with orbital periods longer than 40 d are extremely rare among the 5000+ planets discovered so far. The lack of discoveries of this population poses a challenge…
Masses, Revised Radii, and a Third Planet Candidate in the "Inverted" Planetary System Around TOI-1266
Ryan Cloutier, Michael Greklek-McKeon, Serena Wurmser +40
Is the population of close-in planets orbiting M dwarfs sculpted by thermally driven escape or is it a direct outcome of the planet formation process? A number of recent empirical…
NIGHT: a compact, near-infrared, high-resolution spectrograph to survey helium in exoplanet systems
C. Farret Jentink, V. Bourrier, C. Lovis +5
Among highly irradiated exoplanets, some have been found to undergo significant hydrodynamic expansion traced by atmospheric escape. To better understand these processes in the con…
HD152843 b & c: the masses and orbital periods of a sub-Neptune and a super-puff Neptune
B. A. Nicholson, S. Aigrain, N. L. Eisner +24
We present the characterisation of the two transiting planets around HD 152843 (TOI 2319, TIC 349488688) using an intensive campaign of HARPS-N radial velocities, and two sectors o…
