Frequency analysis of KIC 1573174 : shedding light on the nature of HADS stars
Chenglong Lv, Ali Esamdin, Javier Pascual-Granado +2
We propose that KIC 1573174 is a quadruple-mode Scuti star with pulsation amplitudes between those of the HADS (high-amplitude Delta Scuti star) group and average low-amplitude…
A catalogue of double-mode high amplitude Scuti stars in the Galaxy and their statistical properties
Tao-Zhi Yang, Zhao-Yu Zuo, Xin-Yue Wang +2
We present the first catalogue of double-mode and multi-mode high amplitude Scuti star (HADS) in the Galaxy. The catalogue contains source name, coordinates, radial modes such…
KIC 12602250: A low-amplitude Double-mode Scuti star with Amplitude Modulation
Chenlong Lv, Ali Esamdin, Xiangyun Zeng +3
We propose for the first time that KIC 12602250 is a low-amplitude radial double-mode Scuti star with amplitude modulation. The detailed frequency analysis is given for the lig…
TIC 308396022: a Scuti-- Doradus hybrid with large-amplitude radial fundamental mode and regular g-mode period spacing
Tao-Zhi Yang, Zhao-Yu Zuo, Gang Li +3
We analyse the pulsating behaviour of TIC 308396022 observed by the TESS mission. The star is a high-amplitude Sct star (HADS) that shows a very rich amplitude spectrum using t…
KIC 10975348: A double-mode or triple-mode high-amplitude Scuti star?
Tao-Zhi Yang, Xiao-Ya Sun, Zhao-Yu Zuo +1
In this paper, we analyze the light variations of KIC 10975348 using photometric data delivered from mission. This star is exceptionally faint ( = 18.6 mag), compar…
KIC 8840638: A new eclipsing binary consisting of Scuti-type oscillations with an extremely cold companion star
Tao-Zhi Yang, Zhao-Yu Zuo, Jun-Hui Liu +1
In this paper, we analyze the light variation of KIC 8840638 using high-precision time-series data from mission. The analysis reveals this target is a new Algol-type eclip…
A double-modulation effect detected in a double-mode high-amplitude Scuti star: KIC 10284901
Tao-Zhi Yang, Ali Esamdin
In this paper, we present an analysis of the pulsating behavior of target KIC 10284901. The Fourier transform of the high-precision light curve reveals seven independent f…
Pulsations of the SX Phe Star BL Camelopardalis
Peng Zong, Ali Esamdin, Jian Ning Fu +6
We carried out photometric observations of the SX Phe star BL Cam in 2014, 2017 and 2018 using Nanshan 1-m telescope. In addition to the dominated frequency of 25.5790(3) cd…
Pulsations of the High-Amplitude Scuti Star YZ Bootis
Taozhi Yang, Ali Esamdin, Jianning Fu +5
We present a study on the pulsations of the high-amplitude Scuti star YZ Boo based on photometric observations in Johnson and bands with both the Nanshan 1-m telescope…
A study of variable stars in the open cluster NGC 1582 and its surrounding field
Fang-Fang Song, Ali Esamdin, Lu Ma +4
This paper presents the Charge-Coupled Device time-series photometric observations of the open cluster NGC 1582 and its surrounding field with Johnson B, V and R filters by using N…
