An Eccentric Massive Protobinary Assembled via a Core-merger Parabolic Encounter
Yao Wang, Yichen Zhang, Rubén Fedriani +14
Most massive stars form in binary systems, which profoundly influence their subsequent evolution. However, how such systems form remains poorly understood, with several competing s…
SN 2021pfs: A Type Ia Supernova Likely Affected by Progenitor Metallicity, as Revealed by Comparison with Its Twin Counterpart
Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +16
We present extensive photometric and spectroscopic observations of the normal type Ia supernovae (SNe Ia) 2021pfs, which occurred in the Seyfert 2 galaxy NGC 5427 at a redshift 0.0…
Infrared-excess sources in VVV: candidate debris discs, SED characterization, and variability analysis
P. Esteves, R. K. Saito, C. Chavero +9
Debris disks around main-sequence stars provide important insights into planetary formation and evolution; however, identifying these systems in the Galactic plane, where high inte…
TESS Observations of Seven Newly Identified High-amplitude Scuti Stars
Chenglong Lv, Ali Esamdin, Amir Hasanzadeh +3
We report seven newly identified high-amplitude Scuti (HADS) stars. Among them, two stars (TIC 30977864 and TIC 387379145) exhibit pure radial pulsation without the excitation…
Oscillation Period Properties of Sunspots in the 8-10 m Infrared Band: A Multi-Dataset Analysis

Double-periodic pulsations simultaneously detected in mid-infrared and hard X-ray emissions during an X1.5 flare
Dong Li, Yuyang Ye, Xianyong Bai +1
Quasi-periodic pulsations (QPPs) have been observed in a broad electromagnetic spectrum, encompassing radio, ultraviolet, white light, X-rays, and Gama-rays. Yet, flare-associated…
Research Progress on Solar Small-Scale Dynamo
Wen-Jie Jiang, Lei Ni, Chun-Lan Jin +2
The small-scale solar dynamo theory, as the core mechanism explaining the origin of the persistent, disperse weak magnetic field in the quiet Sun regions, has made significant prog…
Long-term Orbital Period Variations of the Eclipsing Dwarf Nova HT Cas
Aykut Ozdonmez, Huseyin Er, Ilham Nasiroglu +7
We present a comprehensive analysis of the long-term orbital period variations in the short-period eclipsing dwarf nova HT Cas. By combining our new high-precision mid-eclipse time…
Evidence of triggered star formation in the Pillars of Creation from JWST observations
Jing Wen, Bingqiu Chen, Jian Gao +3
Stars form in molecular clouds under the influence of their local environments, yet the role of massive stellar feedback in either triggering or suppressing star formation remains…
Planet engulfment in the chemically anomalous HD 129171/HD 129209 pair
Anne Rathsam, Jorge Meléndez, Rodolfo Smiljanic +2
Binary systems composed of stars with similar parameters should have identical chemical composition. However, many chemically anomalous pairs have been found in the literature, suc…
Multi epoch spectroscopic variability of the B supergiant HD75149
J. Chamoun-Contreras, C. Arcos, N. Machuca +6
Massive stars continuously enrich the surrounding interstellar medium by supplying it with stellar material driven by their powerful winds. B supergiant stars (BSGs) in particular…
The Stellar Abundances and Galactic Evolution Survey (SAGES). V. The First Data Release of the DDO51 Band
Qiqian Zhang, Zhou Fan, Gang Zhao +20
We present the first public data release of DDO51 band from the Stellar Abundances and Galactic Evolution Survey (SAGES), based on Nanshan One-meter Wide-field Telescope (NOWT) obs…
PISP: Projected-Space Inference of Stellar Parameters
Jun-Chao Liang, Yin-Bi Li, A-Li Luo +12
To improve the accuracy and efficiency of high-dimensional stellar parameter inference in large spectroscopic datasets, we propose a projection-assisted parameter-inference framewo…
Searching for Magnetic White Dwarfs in LAMOST DR10
Si-Cheng Yu, Juan-Juan Ren, Vitaly V. Neustroev +7
Magnetic white dwarfs (MWDs) are key to understanding the origin and evolution of magnetic fields in compact stars. While large spectroscopic surveys such as SDSS have greatly expa…
Retarded Stellar Dynamo in Tidally Deformed M Dwarfs
Song Wang, Wenbo Li, Henggeng Han +3
Current studies of stellar dynamos primarily focus on spherical stars, leaving their behavior in distorted stars largely unexplored. We utilize stars of varying distortions to exam…

We present optical photometric and spectroscopic observations of the Type~IIb supernova (SN)~2017ati. It reached the maximum light at about 27~d after the explosion and the light c…
Dynamical Mass Loss at the End of TP-AGB stars
Yingzhen Cui, Song Wang, Xiangcun Meng +3
The thermally pulsating asymptotic giant branch (TP-AGB) phase plays a key role in the evolution of low- to intermediate-mass stars, driving mass loss that influences their final s…
