The GW Vir instability strip in the light of new observations of PG 1159 stars. Discovery of pulsations in the central star of Abell 72 and variability of RX J0122.9-7521
Paulina Sowicka, Gerald Handler, David Jones +9
We present the results of new time series photometric observations of 29 pre-white dwarf stars of PG 1159 spectral type, carried out in the years 2014-2022. For the majority of sta…
The Isaac Newton Telescope monitoring survey of Local Group dwarf galaxies. I. Survey overview and first results for Andromeda I
Elham Saremi, Atefeh Javadi, Jacco Th. van Loon +10
An optical monitoring survey in the nearby dwarf galaxies was carried out with the 2.5-m Isaac Newton Telescope (INT). 55 dwarf galaxies and four isolated globular clusters in the…
IGAPS: the merged IPHAS and UVEX optical surveys of theNorthern Galactic Plane
M. Monguió, R. Greimel, J. E. Drew +47
The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys, IPHAS and UVEX, based on data from the Isaac Newton Telescope (INT) obtained between 2003 an…
Chemical abundances of neutron capture elements in exoplanet-hosting stars
E. Delgado Mena, V. Zh. Adibekyan, P. Figueira +7
To understand the formation and composition of planetary systems it is important to study their host stars composition since both are formed in the same stellar nebula. In this wor…
C/O vs Mg/Si ratios in solar type stars: The HARPS sample
L. Suárez-Andrés, G. Israelian, J. I. González Hernández +4
Aims. We present a detailed study of the Mg/Si and C/O ratios and their importance in determining the mineralogy of planetary companions. Methods. Using 499 solar-like stars from t…
SWEET-Cat update and FASMA. A new minimization procedure for stellar parameters using high-quality spectra
D. T. Andreasen, S. G. Sousa, M. Tsantaki +6
Context: Thanks to the importance that the star-planet relation has to our understanding of the planet formation process, the precise determination of stellar parameters for the ev…
CNO behaviour in planet-harbouring stars. II. Carbon abundances in stars with and without planets using the CH band
L. Suárez-Andrés, G. Israelian, J. I. González Hernández +4
Context. Carbon, oxygen and nitrogen (CNO) are key elements in stellar formation and evolution, and their abundances should also have a significant impact on planetary formation an…
Abundance trend with condensation temperature for stars with different Galactic birth places
V. Adibekyan, E. Delgado-Mena, P. Figueira +9
During the past decade, several studies reported a correlation between chemical abundances of stars and condensation temperature (also known as Tc trend). However, the real astroph…
