EPRV Asteroseismology of the K dwarfs GJ 570 A and GJ 783 A with ESPRESSO. Empirical mode-amplitude scaling in tension with 3D convection simulations

T. L. Campante, Y. Zhou, Y. Li +21

Solar-like oscillations in K dwarfs have intrinsically low amplitudes, making them challenging to detect in space-based photometry. The advent of Extremely Precise Radial Velocity…

TILARA: Template-Independent Line-by-line Algorithm for Radial velocity Analysis. I. Description of the code and application on a Sun-like star

C. San Nicolas Martinez, N. C. Santos, V. Adibekyan +3

Precise radial velocities (RVs) are commonly derived through cross-correlation or template-matching methods, both of which rely on a reference spectrum that can introduce biases wh…

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…

Stellar-activity analysis of the nearby M dwarf GJ 526. Multi-dimensional Gaussian-process modelling of RV, FWHM and S-index

A. K. Stefanov, J. I. González Hernández, A. Suárez Mascareño +17

M dwarfs are the most abundant stars in the Galaxy, and their low masses make them natural favourites for exoplanet radial-velocity (RV) searches. Nevertheless, these stars often d…

Synthesizing Sun-as-a-star flare spectra from high-resolution solar observations

M. De Wilde, A. G. M. Pietrow, M. K. Druett +22

Spatially resolved observations of the Sun and the astronomical sample size of stellar bodies are the respective key strengths of solar and stellar observations. However, the large…

Expanding the frontiers of cool-dwarf asteroseismology with ESPRESSO. Detection of solar-like oscillations in the K5 dwarf Indi

T. L. Campante, H. Kjeldsen, Y. Li +25

Fuelled by space photometry, asteroseismology is vastly benefitting the study of cool main-sequence stars, which exhibit convection-driven solar-like oscillations. Even so, the tin…
