Nicha Leethochawalit, Evan N. Kirby, Richard S. Ellis +2
We present the stellar mass-[Fe/H] and mass-[Mg/H] relation of quiescent galaxies in two galaxy clusters at and . We derive the age, [Fe/H], and [Mg/Fe] for…
Molecular clouds in the Cosmic Snake normal star-forming galaxy 8 billion years ago
Miroslava Dessauges-Zavadsky, Johan Richard, Françoise Combes +12
The cold molecular gas in contemporary galaxies is structured in discrete cloud complexes. These giant molecular clouds (GMCs), with - solar masses and radii of 5-100 p…
The W-subtype active contact binary PZ UMa with a possible more massive tertiary component
X. Zhou, B. Soonthornthum
Two sets of multiple-color () light curves of PZ UMa were observed in dependently with the 2.4 meter telescope at the Thai National Observatory and the 1 meter tele…
V752 Cen -- A triple-lined spectroscopic contact binary with sudden and continuous period changes
X. Zhou, B. Soonthornthum, S. -B. Qian +2
V752 Cen is a triple-lined spectroscopic contact binary. Its multi-color light curves were obtained in the years 1971 and 2018, independently. Photometric analyses reveal that the…
Optimizing exoplanet atmosphere retrieval using unsupervised machine-learning classification
Joshua J. C. Hayes, E. Kerins, S. Awiphan +6
One of the principal bottlenecks to atmosphere characterisation in the era of all-sky surveys is the availability of fast, autonomous and robust atmospheric retrieval methods. We p…
Discovery of tidally-perturbed pulsations in the eclipsing binary U Gru: a pioneering system for tidal asteroseismology
Dominic M. Bowman, Cole Johnston, Andrew Tkachenko +3
The interior physics of stars is currently not well constrained for early-type stars. This is particularly pertinent for multiple systems as binary interaction becomes more prevale…
MOS spectroscopy of protocluster candidate galaxies at z=6.5
Rosa Calvi, José Miguel Rodríguez Espinosa, José Miguel Mas-Hesse +7
The epoch corresponding to a redshift of z is close to full re-ionisation of the Universe, and early enough to provide an intriguing environment to observe the early sta…
Photometric investigation on the W-subtype contact binary V1197 Her
Xiao Zhou, Boonrucksar Soonthornthum
Multi-color light curves of V1197 Her were obtained with the 2.4 meter optical telescope at Thai National Observatory and the Wilson-Devinney (W-D) program is used to model the obs…
HD 965: An extremely peculiar A star with an extremely long rotation period
G. Mathys, I. I. Romanyuk, S. Hubrig +4
Context. One of the keys to understanding the origin of the Ap stars and their significance in the general context of stellar astrophysics is the consideration of the most extreme…
Signature of stochastic acceleration and cooling processes in an outburst phase of the TeV blazar ON 231
