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…
Lack of Significant Orbital-Phase Locking in the Active Phases of the Recurrent Nova T CrB
Songpeng Pei, Xiaowan Zhang, Renzhi Su +6
T Coronae Borealis (T CrB) is a symbiotic recurrent nova (RN) that exhibits both nova eruptions and long-term active phases resembling superoutbursts and normal outbursts. Motivate…
QPEs from Warped Disk Collisions with EMRIs: Brightness-Recurrence Diagram and Gravitational-Wave Follow-up
Bo-An Chen, Bei You, Giovanni Miniutti +11
Quasi-Periodic Eruptions (QPEs) display correlated long/short and strong/weak patterns that remain unexplained by existing flat-disk collision models. We propose that these feature…
KIC 3868420: A high-amplitude Scuti- Dor hybrid star crossing the Hertzsprung gap
Tao-Zhi Yang, Zhao-Yu Zuo
We report a photometric and asteroseismic analysis of KIC 3868420, a newly identified high-amplitude Scuti- Doradus hybrid star located in the Hertzsprung gap - a short-live…
KIC 5623923: A Faint Eclipsing Binary Consisting of Scuti pulsations
Tao-Zhi Yang, Zhao-Yu Zuo, Shi-ping Guo +4
In this paper, we present a detailed analysis of the light variation of KIC 5623923 using high-precision time-series data from the mission. The analysis reveals this targe…
Pulsation Mode Identification and Classification of 46 High-Amplitude Scuti Stars from 50 Candidates with TESS observations
Taozhi Yang, Zhaoyu Zuo
Asteroseismic modelling of high-amplitude Scuti (HADS) variables critically depends on their accurate classification, which provides robust constraints on stellar physical para…
KIC 10855535: An elegant Delta Scuti pulsator with Amplitude and Phase Modulation
Lixian Shen, Ali Esamdin, Chenglong Lv +6
We investigated the pulsating behavior of KIC 10855535 using Kepler 4-year long cadence data. Two independent frequencies were detected: a pulsation frequency F0 = 17.733260(5)d-1…
KIC 9845907: A Scuti star with the first overtone as the dominant frequency and with many equidistant structures in its spectrum
Xiao-Ya Sun, Zhao-Yu Zuo, Tao-Zhi Yang +1
In this paper, we present an analysis of the pulsating behavior of Kepler target KIC 9845907. Using the data from Kepler, we detected 85 significant frequencies, including the firs…
KIC 10417986: Spectroscopic confirmation of the nature of the binary system with a δ Scuti component
Guo-Jie Feng, Ali Esamdin, Jian-Ning Fu +9
KIC 10417986 is a short orbital period (0.0737 d) ellipsoidal variable star with a δ Scuti and γ Doradus hybrid pulsations component discovered by Kepler. The ground-based spectros…
A Weak Modulation Effect Detected in the Light Curves of KIC 5950759: Intrinsic or Instrumental Effect?
Taozhi Yang, A. Esamdin, Fangfang Song +8
In this paper, the high-precision light curves of target KIC 5950759 are analyzed. The Fourier analysis of the long cadence light curve reveals 3 independent frequencies.…
