High-resolution spectroscopy of the young open cluster M 39 (NGC 7092)
J. Alonso-Santiago, A. Frasca, G. Catanzaro +5
M 39 is a nearby young open cluster hardly studied in the last decades. No giant is known among its members and its chemical composition has never been studied. In order to investi…
Cepheid Metallicity in the Leavitt Law (C- MetaLL) survey: IV. The metallicity dependence of Cepheid Period-Luminosity relations
E. Trentin, V. Ripepi, R. Molinaro +10
Classical Cepheids (DCEPs) play a fundamental role in the calibration of the extra-galactic distance ladder which eventually leads to the determination of the Hubble constant(…
First spectroscopic investigation of Anomalous Cepheid variables
V. Ripepi, G. Catanzaro, E. Trentin +12
Anomalous Cepheids (ACEPs) are intermediate mass metal-poor pulsators mostly discovered in dwarf galaxies of the Local Group. However, recent Galactic surveys, including the Gaia D…
TIC 43152097. The first eclipsing binary in NGC 2232
A. Frasca, J. Alonso-Santiago, G. Catanzaro +5
We report the discovery of a low-mass totally eclipsing system in the young (age28 Myr) open cluster NGC2232, during a scrutiny of their TESS light curves. The follow-up st…
Comprehensive spectroscopic and photometric study of pulsating eclipsing binary star AI Hya
F. Kahraman Alicavus, T. Pawar, K. G. Hełminiak +9
The pulsating eclipsing binaries are remarkable systems that provide an opportunity to probe the stellar interior and to determine the fundamental stellar parameters precisely. Esp…
