Detached Eclipsing Binaries in Compact Hierarchical Triples: Triple-lined systems BD+44 2258 and KIC 06525196
Ayush Moharana, K. G. Hełminiak, F. Marcadon +5
Compact Hierarchical Triples (CHT) are systems with the tertiary star orbiting the inner binary in an orbit shorter than 1000 days. CHT with an eclipsing binary as its inner binary…
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…
A Very Metal-poor RR Lyrae Star with a Disk Orbit Found in the Solar Neighborhood
Noriyuki Matsunaga, Akinori Itane, Kohei Hattori +28
Metal-deficient stars are important tracers for understanding the early formation of the Galaxy. Recent large-scale surveys with both photometric and spectroscopic data have report…
Orbital and physical parameters of eclipsing binaries from the ASAS catalogue -- XII. A sample of systems with photometry
K. G. Hełminiak, A. Moharana, T. Pawar +10
We present results of the analysis of light and radial velocity (RV) curves of eight detached eclipsing binaries observed by the All-Sky Automated Survey, which we have followed up…
Eclipsing Binary Populations across the Northern Galactic Plane from the KISOGP survey
Fangzhou Ren, Richard de Grijs, Huawei Zhang +8
We present a catalog of eclipsing binaries in the northern Galactic Plane from the Kiso Wide-Field Camera Intensive Survey of the Galactic Plane (KISOGP). We visually identified 70…
HIDES spectroscopy of bright detached eclipsing binaries from the field - III. Spectral analysis, updated parameters, and new systems
K. G. Hełminiak, M. Konacki, H. Maehara +5
We present the latest results of our spectroscopic observations and refined modelling of a sample of detached eclipsing binaries (DEBs), selected from the } Eclipsing Binar…
Ori and Lib: Two new massive heartbeat binaries
Andrzej Pigulski, Monika K. Kaminska, Krzysztof Kaminski +28
We report the discovery of two massive eccentric systems with BRITE data, Ori and Lib, showing heartbeat effects close to the periastron passage. Lib exhibits shallow e…
High-resolution spectroscopy and abundance analysis of Delta Scuti stars near the Gamma Doradus instability strip
F. Kahraman Aliçavuş, E. Niemczura, M. Polińska +5
Scuti stars are remarkable objects for asteroseismology. In spite of decades of investigations, there are still important questions about these pulsating stars to be answered,…
KIC 4150611: a rare multi-eclipsing quintuple with a hybrid pulsator
K. G. Hełminiak, N. Ukita, E. Kambe +5
We present the results of our analysis of KIC 4150611 (HD 181469) - an interesting, bright quintuple system that includes a hybrid Sct/ Dor pulsator. Four periods of eclipse…
HIDES spectroscopy of bright detached eclipsing binaries from the field - II. Double- and triple-lined objects
K. G. Hełminiak, N. Ukita, E. Kambe +5
We present the results of our spectroscopic observations of eight detached eclipsing binaries (DEBs), selected from the Eclipsing Binary Catalog. Radial velocities (RVs) w…
HIDES spectroscopy of bright detached eclipsing binaries from the field - I. Single-lined objects
K. G. Hełminiak, N. Ukita, E. Kambe +5
We present results of our spectroscopic observations of nine detached eclipsing binaries (DEBs), selected from the Eclipsing Binary Catalog, that only show one set of spec…
OISTER Optical and Near-Infrared Observations of the Super-Chandrasekhar Supernova Candidate SN 2012dn: Dust Emission from the Circumstellar Shell
