ASTRAFier: A Novel and Scalable Transformer-based Stellar Variability Classifier
Paul F. X. Gregory, Jeroen Audenaert, Mykyta Kliapets +5
Photometric missions such as Kepler and TESS have generated millions of light curves covering almost the entire sky, offering unprecedented opportunities to study stellar variabili…
The evolution of PUCHEROS from a basic to a competitive tool for stellar astrophysics
Luca Antonucci, Leonardo Vanzi, Abner Zapata +16
We present PUCHEROS +, a new spectrograph developed as an enhanced version of PUCHEROS (Pontificia Universidad Catolica High Echelle Resolution Optical Spectrograph), which was the…
PLATOSpec: a precise spectrograph in support of space missions
P. Kabáth, M. Skarka, A. Hatzes +42
The upcoming space missions that will characterize exoplanets, such as PLATO and Ariel, will collect huge amounts of data that will need to be complemented with ground-based observ…
Ondr}ejov echelle spectrograph, ground based support facility for exoplanet missions
Petr Kabath, Marek Skarka, Silvia Sabotta +18
Fulfilling the goals of space-based exoplanetary transit surveys, like Kepler and TESS, is impossible without ground-based spectroscopic follow-up. In particular, the first-step ve…
How far can we trust published TESS periods?
Zdeněk Mikulášek, Marek Skarka
Possible inaccuracies in the determination of periods from short-term time series caused by disregard of the real course of light curves and instrumental trends are documented on t…
Extended Aperture Photometry of K2 RR Lyrae stars
Emese Plachy, László Molnár, Attila Bódi +6
The \textit{Kepler} space telescope observed thousands of RR Lyrae stars in the K2 mission. In this paper we present our photometric solutions using extended apertures in order to…
K2 Photometry of RR Lyrae Stars
E. Plachy, L. Molnár, A. Bódi +5
Thousands of RR Lyrae stars have been observed by the \textit{Kepler} space telescope so far. We developed a photometric pipeline tailored to the light variations of these stars, c…
