  • Triggered star formation in OB associations 
    Vaidya, Kaushar (CUP, 2006-08)
    We present causal and positional evidence of triggered star formation in bright-rimmed clouds in OB associations, e.g., Ori OB1, and Lac OB1, by photoionization. The triggering process is seen also on a much larger scale ...
  • Star formation toward IRAS 10427-6032 
    Vaidya, Kaushar (Memorie della Societa Astronomica Italiana, 2017)
    We study a 5arcmin × 5arcmin region surrounding a compact H II region IRAS 10427-6032 using multi-wavelength observations. We identified 29 Class II and 5 Class I young stellar object (YSO) candidates, most of which are ...
  • Star formation toward the H II region IRAS 10427-6032 
    Vaidya, Kaushar (Elsevier, 2018-08)
    The formation and properties of star clusters formed at the edges of the H II regions are poorly known. In this paper, we study stellar content, physical conditions, and star formation processes around a relatively unknown ...
  • Study of Blue Straggler Stars in Open Cluster NGC 2506 using UVIT/AstroSat 
    Vaidya, Kaushar (COSPAR Scientific Assembly, 2022-07)
    Blue straggler stars (BSS) are one of the exotic stellar populations that prolong their main-sequence lifetimes by acquiring extra mass through either mass transfer or complete merger in a binary or multiple stellar system, ...
  • Studies of Blue Stragglers in star clusters with AstroSat 
    Vaidya, Kaushar (COSPAR Scientific Assembly, 2022-07)
    We present an overview of Blue Stragglers (BSs) studies in star clusters using UVIT observations onboard AstroSat. The formation of BSs has puzzled scientists for several decades since their discovery. Two main scenarios ...
  • A UVIT/AstroSat Study of Blue Straggler Stars of NGC 7789 
    Vaidya, Kaushar (COSPAR Scientific Assembly, 2022-07)
    We present a study of blue straggler stars (BSS) of open cluster NGC 7789 using the Ultraviolet (UV) data from the UVIT/AstroSat. NGC 7789 is a ∼1.6 Gyr old, populous open cluster located at ∼2000 pc. There are 13 BSS ...
  • Discovery of white dwarf companions of blue metal-poor stars using UVIT/AstroSat 
    Vaidya, Kaushar (American Physical Society, 2023)
    Blue metal-poor (BMP) stars are main-sequence stars that appear bluer and more luminous than normal turn-off stars of metal-poor globular clusters. These stars are believed to be either field blue straggler stars (FBSS) ...
  • Study of blue metal-poor stars using UVIT/AstroSat 
    Vaidya, Kaushar (ARXIV, 2023-07)
    Blue metal-poor stars are main-sequence stars that are bluer and brighter than typical turn-off stars in metal-poor globular clusters. They are thought to have either evolved through post-mass transfer mechanisms as field ...
  • Hot Stellar Populations of Berkeley 39 using Swift/UVOT 
    Vaidya, Kaushar (ARXIV, 2023-08)
    Open clusters are excellent tools to probe the history of the Galactic disk and properties of star formation. In this work, we present a study of an old age open cluster Berkley 39 using the observations from UVOT instrument ...
  • Determination of dynamical ages of open clusters through the A+ parameter – II 
    Vaidya, Kaushar (OUP, 2023-09)
    Blue straggler stars (BSS), one of the most massive members of star clusters, have been used for over a decade to investigate mass segregation and estimate the dynamical ages of globular clusters (GCs) and open clusters ...
  • UOCS – XI. Study of blue straggler stars in open cluster NGC 7142 using UVIT/AstroSat 
    Vaidya, Kaushar (OUP, 2023-12)
    We present a study of blue straggler stars (BSSs) of open cluster NGC 7142 using AstroSat/UVIT data and other archival data. Using a machine-learning-based algorithm, ML-MOC, on Gaia DR3 data, we find 546 sources as cluster ...
  • UOCS-XII. A study of open cluster NGC 6940 using UVIT/AstroSat cluster properties and exotic populations 
    Vaidya, Kaushar (OUP, 2023-12)
    We study an open cluster NGC 6940 using AstroSat/UVIT (Ultraviolet Imaging Telescope) data and other archival data. This is an intermediate age cluster (∼1 Gyr), located at about 770 pc distance, harbouring several exotic ...
  • PRLNIC3 observations of star forming cloud L1340 
    Vaidya, Kaushar (Bulletin of the Astronomical Society of India, 2001)
    Due mainly to high extinction in optical, the structure of our galaxy, Milky Way, is not very well understood. The Galactic disk and bulge contain a host of heavily reddened open clusters which are deeply embedded within ...
  • Constraining convection parameters from the light curve shapes of pulsating white dwarf stars: the cases of EC 14012-1446 and WD 1524-0030 
    Vaidya, Kaushar (IOP, 2008)
    Montgomery [1] developed a method to probe convection in pulsating white dwarf stars which allows the recovery of the thermal response time of the convection zone by fitting observed nonsinusoidal light curves. He applied ...
  • Field blue straggler stars: discovery of white dwarf companions to blue metal-poor stars using UVIT/AstroSat 
    Vaidya, Kaushar (OUP, 2023-08)
    Blue metal-poor (BMP) stars are the main-sequence stars that appear bluer and more luminous than normal turn-off stars of metal-poor globular clusters. They are believed to be either field blue straggler stars (FBSS) formed ...
  • Tidal disruption of the aged open cluster Berkeley 17 
    Vaidya, Kaushar (IOP, 2017)
    Berkeley 17 is known to show a core-tail morphology. Pan-STARRS 1 photometry complete to gP1 ≈ 21.5 mag reveals the effect of mass segregation between the core and the tail (and an antitail). Furthermore, there is an overall ...
  • Discovery of double BSS sequences in the old Galactic open cluster Berkeley 17 
    Vaidya, Kaushar (OUP, 2022-10)
    Blue straggler stars (BSS) are peculiar objects which normally appear as a single broad sequence along the extension of the main sequence. Only four globular clusters (GCs) have been observed to have two distinct and ...
