An analysis of four stellar rings
E. Paunzen, J. Florian, A. Gütl-Wallner +9
About 50 years ago, one thousand ring-like structures (called stellar-rings) were discovered by Isserstedt (1968). They were believed to be groups of young stars formed by shell-li…
WISE J005128.08+645651.7: An enigmatic R Coronae Borealis star
J. Budaj, K. Bernhard, I. Hubeny
Context. R Coronae Borealis (RCB) stars are hydrogen-deficient and carbon-rich (HdC) supergiants that likely originate from a merger of two white dwarfs. As such they are not expec…
The Inbound Gas and Dust Evolution of Interstellar Comet 3I/ATLAS from Optical Spectroscopy and Multi-band Photometry
Toni Santana-Ros, Alexey Sergeyev, Oleksandra Ivanova +9
Interstellar objects (ISOs) provide direct constraints on the composition and evolution of extrasolar planetary systems. As the third confirmed ISO, comet 3I/ATLAS offers a rare op…
De mora luminis: Roemer's discovery 350 years later
Fabio Falchi, Riccardo Furgoni, Paolo Gattillo +1
350 years from the 1676 announcement of the Roemer's discovery that light propagates with finite speed, we present our observations using eyes with telescopes having similar resolu…
A comprehensive study of comet 67P/Churyumov-Gerasimenko in the 2021/2022 apparition. II. Colorimetry, polarimetry, modeling
Vera Rosenbush, Oleksandra Ivanova, Johannes Markkanen +5
This paper presents the second part of our multi-technique observational study of comet 67P during its 2021-2022 apparition. While the first paper focused on photometry and spectro…
Revision of the Detached Eclipsing System IR Cas from TESS Observations, Ground-Based Photometry and Spectroscopy
Matúš Kamenec, Pavol Gajdoš, Martin Vaňko +3
We present a new photometric and spectroscopic analysis of detached eclipsing binary IR Cas based on TESS observations, supplementary ground-based photometry in Sloan , $…
