The extended atmosphere and circumstellar environment of the cool evolved star VX Sagittarii as seen by MATISSE
A. Chiavassa, K. Kravchenko, M. Montargès +50
Context. VX Sgr is a cool, evolved, and luminous red star whose stellar parameters are difficult to determine, which affects its classification. Aims. We aim to spatially resolve t…
Coherent and incoherent superposition of transition matrix elements of the squeezing operator
Sandor Varro
We discuss the general matrix elements of the squeezing operator between number eigenstates of a harmonic oscillator (which may also represent a quantized mode of the electromagnet…
Automated Extended Aperture Photometry of K2 variable stars
Attila Bódi, Pál Szabó, Emese Plachy +2
Proper photometric data are challenging to obtain in the K2 mission of the Kepler space telescope due to strong systematics caused by the two-wheel-mode operation. It is especially…
Evolution of dust in protoplanetary disks of eruptive stars
Eduard Vorobyov, Aleksandr M. Skliarevskii, Tamara Molyarova +6
Luminosity bursts in young FU Orionis-type stars warm up the surrounding disks of gas and dust, thus inflicting changes on their morphological and chemical composition. In this wor…
Recurrent strong outbursts of an EXor-like young eruptive star Gaia20eae
Fernando Cruz-Sáenz de Miera, Ágnes Kóspál, Péter Ábrahám +21
We present follow-up photometric and spectroscopic observations, and subsequent analysis of Gaia20eae. This source triggered photometric alerts during 2020 after showing a 3…
Non-radial modes in classical Cepheids. What to look for in spectroscopy?
H. Netzel, K. Kolenberg
Recent photometric observations of first-overtone classical Cepheids and RR Lyrae stars have led to the discovery of additional frequencies showing a characteristic period ratio of…
