On the contradictory case of the binary system HD 81809 hosting two pulsating solar-like stars observed by TESS
Maria Pia Di Mauro, Camilla Pezzotti, Nuno Moedas +8
We present a new comprehensive study of HD81809, a nearby binary system of two solar-like stars showing high-amplitude X-ray emission and a well-defined 8-year solar-like magnetic…
Pulsating and Non-pulsating Components of Detached Eclipsing Binaries in the Scuti instability strip
Filiz Kahraman Aliçavuş, Fahri Aliçavuş, Zeynep Çelik Orhan +3
Pulsating detached eclipsing binary systems are crucial for studying the internal structure of oscillating stars. These systems are advantageous because binary effects on pulsation…
High-resolution Spectroscopic Metallicities of Milky Way Cepheid Standards and their impact on the Leavitt Law and the Hubble constant
Anupam Bhardwaj, Adam G. Riess, Giovanni Catanzaro +10
Milky Way Cepheid variables with accurate {\it Hubble Space Telescope} photometry have been established as standards for primary calibration of the cosmic distance ladder to achiev…
Rotation and activity in late-type members of the young cluster ASCC 123
A. Frasca, J. Alonso-Santiago, G. Catanzaro +1
ASCC 123 is a little-studied young and dispersed open cluster. Recently, we conducted the first research devoted to it. In this paper, we complement our previous work with TESS pho…
Cepheid metallicity in the Leavitt law (C-MetaLL) survey -- III. Simultaneous derivation of the Gaia parallax offset and Period-Luminosity-Metallicity coefficients
R. Molinaro, V. Ripepi, M. Marconi +7
Classical Cepheids (DCEPs) are the most important standard candles in the extra-galactic distance scale thanks to the Period-Luminosity (), Period-Luminosity-Color ($\rm PL…
Discovery and origin of the radio emission from the multiple stellar system KQVel
P. Leto, L. M. Oskinova, C. S. Buemi +20
KQVel is a binary system composed of a slowly rotating magnetic Ap star with a companion of unknown nature. In this paper, we report the detection of its radio emission. We conduct…
