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…

Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri

Gaia Collaboration, K. Weingrill, A. Mints +400

Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…

Gaia Focused Product Release: Radial velocity time series of long-period variables

Gaia Collaboration, M. Trabucchi, N. Mowlavi +403

The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…

HADES RV programme with HARPS-N at TNG XIV. A candidate super-Earth orbiting the M-dwarf GJ 9689 with a period close to half the stellar rotation period

J. Maldonado, A. Petralia, M. Damasso +27

Context. It is now well-established that small, rocky planets are common around low-mass stars. However, the detection of such planets is challenged by the short-term activity of t…

A celestial matryoshka: Dynamical and spectroscopic analysis of the Albireo system

Ronald Drimmel, Alessandro Sozzetti, Klaus-Peter Schroeder +4

We present a spectroscopic characterisation and a new orbital solution for the binary system beta Cyg Aa/Ac (MCA 55), the primary component (beta Cyg A) of the well-known wide doub…

HADES RV Programme with HARPS-N at TNG XII. The abundance signature of M dwarf stars with planets

J. Maldonado, G. Micela, M. Baratella +27

Most of our current knowledge on planet formation is still based on the analysis of main-sequence, solar-type stars. Conversely, detailed chemical studies of large samples of M-dwa…

Three Years of HARPS-N High-Resolution Spectroscopy and Precise Radial Velocity Data for the Sun

X. Dumusque, M. Cretignier, D. Sosnowska +35

The solar telescope connected to HARPS-N has been observing the Sun since the summer of 2015. Such high-cadence, long-baseline data set is crucial for understanding spurious radial…

Photometric rotation periods for 107 M dwarfs from the APACHE survey

P. Giacobbe, M. Benedetto, M. Damasso +13

We present rotation period measurements for 107 M dwarfs in the mass range observed within the context of the APACHE photometric survey. We measure rotation per…

HADES RV Programme with HARPS-N at TNG. X. The non-saturated regime of the stellar activity-rotation relationship for M-Dwarfs

E. González-Álvarez, G. Micela, J. Maldonado +22

Aims. We aim to extend the relationship between X-ray luminosity (Lx) and rotation period (Prot) found for main-sequence FGK stars and test whether it also holds for early-M dwarfs…

HADES RV Programme with HARPS-N at TNG. VII. Rotation and activity of M-Dwarfs from time-series high-resolution spectroscopy of chromospheric indicators

A. Suárez Mascareño, R. Rebolo, J. I. González Hernández +28

We aim to investigate the presence of signatures of magnetic cycles and rotation on a sample of 71 early M-dwarfs from the HADES RV programme using high-resolution time-series spec…
