Aims: We aim to study the spot evolution and differential rotation in the magnetically active cool K-type giant star sigma Gem from broadband photometry and continuous spectroscopi…
Infection dynamics of COVID-19 virus under lockdown and reopening
Jakub Svoboda, Josef Tkadlec, Andreas Pavlogiannis +2
Motivated by COVID-19, we develop and analyze a simple stochastic model for a disease spread in human population. We track how the number of infected and critically ill people deve…
Vacuum ultraviolet photoabsorption spectroscopy of space-related ices: Formation and destruction of solid carbonic acid upon 1~keV electron irradiation
S. Ioppolo, Z. Kanuchová, R. L. James +7
Carbonic acid (H2CO3) is a weak acid relevant to astrobiology which, to date, remains undetected in space. Experimental work has shown that the beta-polymorph of H2CO3 forms under…
Age-metallicity dependent stellar kinematics of the Milky Way disc from LAMOST and Gaia
Yaqian Wu, Maosheng Xiang, Yuqin Chen +5
We investigate the stellar kinematics of the Galactic disc in 7 13\,kpc using a sample of 118\,945 red giant branch (RGB) stars from LAMOST and Gaia. We characterize th…
Mode Angular Degree Identification in Subgiant Stars with Convolutional Neural Networks based on Power Spectrum
Minghao Du, Shaolan Bi, Xianfei Zhang +3
Identifying the angular degrees of oscillation modes is essential for asteroseismology and depends on visual tagging before fitting power spectra in a so-called peakbagging ana…
Inverse analysis of asteroseismic data: a review
Earl P. Bellinger, Sarbani Basu, Saskia Hekker
Asteroseismology has emerged as the best way to characterize the global and internal properties of nearby stars. Often, this characterization is achieved by fitting stellar evoluti…
SOXS: Effects on optical performances due to gravity flexures, temperature variations, and subsystems alignment
Ricardo Zanmar Sanchez, Matteo Aliverti, Matteo Munari +43
SOXS (Son Of X-Shooter) is the new medium resolution wide-band spectrograph to be installed at the 3.6m New Technology Telescope (NTT) in La Silla. SOXS will offer simultaneous wav…
The SOXS scheduler for remote operation at LaSilla:Concept and design
Marco Landoni, Dave Young, Laurent Marty +46
In this paper we present the SOXS Scheduler, a web-based application aimed at optimising remote observations at the NTT-ESO in the context of scientific topics of both the SOXS Con…
Asteroseismology of luminous red giants with Kepler. II. Dependence of mass loss on pulsations and radiation
Jie Yu, Saskia Hekker, Timothy R. Bedding +5
Mass loss by red giants is an important process to understand the final stages of stellar evolution and the chemical enrichment of the interstellar medium. Mass-loss rates are thou…
Charged polarons and molecules in a Bose-Einstein Condensate
Esben Rohan Christensen, Arturo Camacho-Guardian, Georg M. Bruun
We investigate the properties a mobile ion immersed in a Bose-Einstein condensate (BEC) using different theoretical approaches. A coherent state variational ansatz predicts that th…
The updated BaSTI stellar evolution models and isochrones: II. alpha-enhanced calculations
A. Pietrinferni, S. L. Hidalgo, S. Cassisi +7
This is the second paper of a series devoted to present an updated release of the BaSTI ( a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library. Following the…
Testing the intrinsic scatter of the asteroseismic scaling relations with Kepler red giants
Yaguang Li, Timothy R. Bedding, Dennis Stello +3
Asteroseismic scaling relations are often used to derive stellar masses and radii, particulaly for stellar, exoplanet, and Galactic studies. It is therefore important that their pr…
Luminous Red Nova AT 2019zhd, a new merger in M 31
A. Pastorello, M. Fraser, G. Valerin +20
We present the follow-up campaign of the luminous red nova (LRN) AT~2019zhd, the third event of this class observed in M 31. The object was followed by several sky surveys for abou…
TESS observations of Cepheid stars: first light results
E. Plachy, A. Pál, A. Bódi +33
We present the first analysis of Cepheid stars observed by the TESS space mission in Sectors 1 to 5. Our sample consists of 25 pulsators: ten fundamental mode, three overtone and t…
Prospects for Galactic and stellar astrophysics with asteroseismology of giant stars in the Continuous Viewing Zones and beyond
J. Ted Mackereth, Andrea Miglio, Yvonne Elsworth +30
The NASA- mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We present a first look at the prospects for…
Short-term variability and mass loss in Be stars VI. Frequency groups in Cas detected by TESS
Jonathan Labadie-Bartz, Dietrich Baade, Alex C. Carciofi +5
In photometry of Cas (B0.5 IVe) from the SMEI and BRITE-Constellation satellites, indications of low-order non-radial pulsation have recently been found, which would establish…
