A super-Earth and a mini-Neptune near the 2:1 MMR straddling the radius valley around the nearby mid-M dwarf TOI-2096

F. J. Pozuelos, M. Timmermans, Benjamin V. Rackham, L. J. Garcia et autres

Several planetary formation models have been proposed to explain the observed abundance and variety of compositions of super-Earths and mini-Neptunes. In this context, multitransiting systems orbiting low-mass stars whose planets are close to the radius valley are benchmark systems, which help to …

Quaternionic Transform: A new Light on the Solar Power Spectrum

R. Garrido, A. Ayala, J. Pascual-Granado, José Gómez-Torrecillas et autres

Asteroseismology, that is, the use of the frequency content of a time series caused by variations in brightness or radial velocity of a stellar object, is based on the hypothesis that such a series is harmonic and therefore can be described by …

Determining the seismic age of the young open clusterα Per using δ Scuti stars

Antonio García Hernández, Juan Carlos Suárez, J. Pascual-Granado, S. Barceló Forteza et autres

ABSTRACT In this work, we aim at constraining the age of the young open cluster Melotte 20, known as α Per, using seismic indices. The method consists of the following steps: (1) Extract the frequency content of a sample of stars in …

Study of rotational splittings in δ Scuti stars using pattern finding techniques

A. Ramón, Juan Carlos Suárez, J. R. Rodón, J. Pascual-Granado et autres

ABSTRACT Detecting and understanding rotation in stellar interiors is nowadays one of the unsolved problems in stellar physics. Asteroseismology has been able to provide insights on rotation for the Sun, solar-like stars, and compact objects like white dwarfs. However, this is still …

Erratum: Study of the low-order Δν–ρ¯ relation for moderately-rotating δ Scuti stars and its impact on their characterization

J. E. Rodríguez-Martín, Juan Carlos Suárez, J. R. Rodón

The paper ‘Study of the low-order Δν–|${\bar{\rho }}$| relation for moderately-rotating δ Scuti stars and its impact on their characterization’ was published in MNRAS, 2020, 498, 1700–1709. After publication of the paper, a systematic error was found that affected the results presented …

GJ 273: On the formation, dynamical evolution, and habitability of a planetary system hosted by an M dwarf at 3.75 parsec

F. J. Pozuelos, Juan Carlos Suárez, G. C. de Elía, Z. M. Berdinas̃ et autres

Context. Planets orbiting low-mass stars such as M dwarfs are now considered a cornerstone in the search for planets with thepotential to harbour life. GJ 273 is a planetary system orbiting an M dwarf only 3.75 pc away, which is composed of …

Toward a New Paradigm in the Analysis of Asteroseismic Lightcurves

Juan Carlos Suárez, R. Garrido, J. Pascual-Granado, Antonio García Hernández et autres

This paper aims at being a provocative guide to the future of asteroseismology from the perspective of the analysis of time series, where the fundamentals of harmonic analysis are subjected to stress tests. In this context, we give an annotated summary of …

The first view of $δ$ Scuti and $γ$ Doradus stars with the TESS mission

V. Antoci, M. S. Cunha, D. M. Bowman, Simon J. Murphy et autres

We present the first asteroseismic results for $δ$ Scuti and $γ$ Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilise the 2-min cadence TESS data for a sample of 117 stars to classify their behaviour regarding variability …
