Flickering Candles: Cepheid Variable Stars
Cepheid variable stars change their intrinsic luminosity in a Cepheid variablespecific manner with periods ranging from days to months. In the early...

Variable stars in the field of the Galactic bulge globular cluster NGC 6522
We present a comprehensive analysis of the variable stars projected on the field of the Galactic bulge globular cluster NGC 6522, offering valuable...

Revised Version of the New Catalogue of Suspected Variable Stars, NSV Release 2
AbstractWe present NSV Release 2, an electronic version of the “New Catalogue of Suspected Variable Stars”. A detailed file-by-file description of...

Time Domain Astronomy Case: Use of Large Photometric Surveys for Study of Variable Stars
AbstractLong-period eclipsing binaries (variables) are a valuable source of data for calculating stellar masses. Such objects have a sufficient...

Stars That Breathe
Stars which show a variation in their brightness are called variable stars. Pulsating variables are intrinsic variable stars whose brightness changes...

TYC 1417-891-1 and TYC 1478-742-1: Eclipsing Variable Stars. The Gaia EDR3 and TESS Photometric Data
Based on the TESS (Transiting Exoplanet Survey Satellite) phase dependent light curves, we confirm the eclipsing type variability nature for two...

Herbig Stars
Herbig Ae/Be stars are young contracting stars on the radiative track in the HR diagram on their way to the main sequence. These stars provide a...

The Digitized First Byurakan Survey Database Late-Type Stars Candidates. New Confirmations. II
Three new carbon C stars was confirmed among the sample of the Late-Type Stars candidates, selected on the Digitized First Byurakan Survey (DFBS)...

Isolated Neutron Stars
Non-accreting neutron stars display diverse characteristics, leading us to classify them into several groups. This chapter is an observational driven...

Formation of Stars
In this chapter we discuss the formation of stars. The formation of stars can be observed in various gas nebulae, and the formation process is...

Quark-hadron deconfinement phase transition and massive hybrid stars
The stellar configurations of quark stars have been studied using perturbative QCD (pQCD). The effective equation of state (EoS) for cold quark...

Periodicity of Flare Frequency of Active Flare Stars Detected by Tess
Data from the TESS orbital observatory are used to study the most active flare stars indicating 100 or more flares during the period from July 2018...

Axion stars in MGD background
The minimal geometric deformation (MGD) paradigm is here employed to survey axion stars on fluid branes. The finite value of the brane tension...

Parameters and the Eddington pulsation constant of Galactic RRab stars
For Galactic RRab stars 121 empirical and semiempirical metallicity–absolute magnitude relations known since 1990 are analyzed. For these variables,...

Spherically symmetric anisotropic strange stars
In this work, we made an extensive study about the possible presence of anisotropies in strange stars. To accomplish this task, we use three...

Distribution of Young Spectroscopic Binary Stars by Mass Ratio and Eccentricity
AbstractData were collected on 83 young double-lined spectroscopic binary stars, among them—Herbig Ae/Be stars, T Tauri stars and red dwarfs....

Spin-0 bosons near rotating stars
In this work we study the effects of rotating stars on the behavior of bosons close to their surfaces. For this task, metrics determined by the...

Neutron stars in the Witten-Sakai-Sugimoto model
We utilize the top-down holographic QCD model, the Witten-Sakai-Sugimoto model, in a hybrid setting with the SLy4, soft chiral EFT and stiff chiral...

Science with a Small Two-Band UV-Photometry Mission II: Observations of Stars and Stellar Systems
We outline the impact of a small two-band UV-photometry satellite mission on the field of stellar physics, magnetospheres of stars, binaries, stellar...
