Lithium depletion in solar analogs: age and mass effects
Anne Rathsam, Jorge Meléndez, Gabriela Carvalho Silva
The main goal of this work is to evaluate the correlation between Li abundance, age, and mass. Using high-quality ESO/HARPS data (R 115 000; 270 SNR 1000), w…
Universal interface fluctuations in the contact process
B. G. Barreales, J. J. Meléndez, R. Cuerno +1
We study the interface representation of the contact process (CP) at its directed-percolation critical point, where the scaling properties of the interface can be related to those…
A Jupiter analogue and a cold Super-Neptune orbiting the solar-twin star HIP 104045
Thiago Ferreira, Jorge Meléndez, Diego Lorenzo-Oliveira +3
We present the discovery of two planets around the solar twin HIP 104045 via radial velocity data obtained with the ESO/HARPS spectrograph as part of the Solar Twin Planet Search o…
TOI-1055 b: Neptunian planet characterised with HARPS, TESS, and CHEOPS
A. Bonfanti, D. Gandolfi, J. A. Egger +89
TOI-1055 is a Sun-like star known to host a transiting Neptune-sized planet on a 17.5-day orbit (TOI-1055 b). Radial velocity (RV) analyses carried out by two independent groups us…
Is the solar spectrum latitude dependent? An investigation with SST/TRIPPEL
Dan Kiselman, Tiago Pereira, Bengt Gustafsson +3
Context: In studies of the solar spectrum relative to spectra of solar twin stars, it has been found that the chemical composition of the Sun seems to depart systematically from th…
