A Decade of Solar High-Fidelity Spectroscopy and Precise Radial Velocities from HARPS-N
X. Dumusque, K. Al Moulla, M. Cretignier +53
We recently released 10 years of HARPS-N solar telescope and the goal of this manuscript is to present the different optimisations made to the data reduction, to describe data cura…
Granulation on a quiet K dwarf: HD 166620 I. Spectral signatures as a function of line-formation temperature
Ancy Anna John, Khaled Al Moulla, Niamh K. O'Sullivan +14
As Radial velocity (RV) spectrographs reach unprecedented precision and stability below 1 m/s, the challenge of granulation in the context of exoplanet detection has intensified. D…
Confronting compositional confusion through the characterisation of the sub-Neptune orbiting HD 77946
L. Palethorpe, A. Anna John, A. Mortier +29
We report on the detailed characterization of the HD 77946 planetary system. HD 77946 is an F5 ( = 1.17 M, = 1.31 R) star, which hosts a transiting p…
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…
A hot mini-Neptune and a temperate, highly eccentric sub-Saturn around the bright K-dwarf TOI-2134
F. Rescigno, G. Hébrard, A. Vanderburg +64
We present the characterisation of an inner mini-Neptune in a 9.22920050.0000063 day orbit and an outer mono-transiting sub-Saturn planet in a 95.50 day orbi…
The GAPS programme at TNG XLIV. Projected rotational velocities of 273 exoplanet-host stars observed with HARPS-N
M. Rainer, S. Desidera, F. Borsa +25
The leading spectrographs used for exoplanets' sceince offer online data reduction softwares (DRS) that yield as an ancillary result the full-width at half-maximum (FWHM) of the cr…
