Search of Short-Period Pulsating Variables(I) [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1996
CCD differential photometry was carried out for seven stars in the "New Catalogue of Suspected Variable Stars" in order to discover new short-period pulsating variables such as low and high amplitude δ Scuti stars and RR Lyrae stars.

Variability in Early Post-main-sequence Stars in Globular Cluster NGC 3201

open access: yesThe Astronomical Journal, 2023
In this paper we study stellar variability in the globular cluster NGC 3201 in the magnitude range V = 16–17, corresponding to the subgiant branch and blue stragglers region of the cluster.

New SB1s with Spectroscopic Orbits from LAMOST-LRS

open access: yesThe Astrophysical Journal Supplement Series, 2023
The LAMOST Low-Resolution Spectroscopic (LAMOST-LRS) Survey provides radial velocities of 10 million stars. These observations can be used to identify new single-lined spectroscopic binaries (SB1s) with their preliminary spectroscopic orbits.

How rotation affects masses and ages of classical Cepheids

open access: yesEPJ Web of Conferences, 2017
Classical Cepheid variable stars are both sensitive astrophysical laboratories and accurate cosmic distance tracers. We have recently investigated how the evolutionary effects of rotation impact the properties of these important stars and here provide an

Research Paper: Analytical Solution of the Equation Related to the Oscillations of Ap Pulsating Stars Under the Effect of Rotation [PDF]

open access: yesفیزیک کاربردی ایران
Rapidly oscillating Ap stars are a special type of variable stars that are not in hydrostatic equilibrium. Their pulsation period is very short compared to other stars of this group and is less than one hour.

Eight Phase-step δ Scuti Variables in TESS Data

open access: yesThe Astronomical Journal
Analysis of the previously classified delta Scuti variable star MW Camelopardalis using data from the Transiting Exoplanet Survey Satellite sparked a deeper inquiry due to unexpected patterns within the target’s observed − calculated ( O − C ) diagram ...

Photometric Study of Three Short Period Variable Stars

open access: yesRevista Mexicana de Astronomía y Astrofísica, 2020
We have obtained uvby - β photoelectric photometry with the 0.84 m telescope at the San Pedro Mártir Observatory, México, for the stars HD 115520, HD 220735 and HD 26738. The first two had been previously determined to be variables whereas the last one is being reported here as a new variable.

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching
