Photometric and Spectroscopic Analysis of Five Am Stars
Gireesh C. Joshi
The photometric analysis of sample Am stars is carried out to determine the stellar characteristics and to constrain the stellar dynamics. The spectroscopic analysis of the studied…
Effect of Blue Component Stars in Parameters of NGC 6866
Gireesh C. Joshi
The open star clusters (OSC) are important tracers for understanding the Galactic evolution. The parametric study of these astronomical-objects is crucial task due to the appearing…
Photometric Search for variable stars in the field of two Northern open clusters, DOLIDGE 14 and NGC 1960
Gireesh C. Joshi
The aim of present work is extract and analyses the light curves of the stars in the field of two clusters, NGC 1960 and DOLIDZE 14. The photometric calibration is performed by com…
Stellar Variability with Photometric and Spectroscopic Analysis of five Am Field Stars
Gireesh C. Joshi
The spectroscopic and photometric analysis of sample Am stars are carried out to determine the stellar characteristics of each studied star. The CCD photometric analysis of HD 9885…
IC 361:- Near infrared and UBVRI photometric Analysis
Gireesh C. Joshi
We present here the detailed optical and infra-red photometric analysis of the open star cluster IC 361. On studying the radial density profile, radial extent of the cluster is fou…
Test of depending frequencies of the variable Stars of OC: NGC 6866
Gireesh C. Joshi
The search of secondary pulsations is carried out to understand the possible relations among the known parameters of variables of the cluster, NGC 6866. These pulsations arise due…
Dynamical analysis of NGC 110: cluster of fainter stars or data fluctuation?
Gireesh C. Joshi
The stellar enhancement of the cluster NGC 110 is investigated in various optical and infrared (IR) bands. The radial density profile of the IR region does not show a stellar enhan…
Search of Secondary Pulsation Modes: Globular cluster (NGC 6496)
Gireesh C. Joshi, R. K. Tyagi
The Fourier-discrete-peridogram are used to identify pulsation modes in variables. We have found two pulsation modes in V1 and V2 among 13 new variables as described by Abbas et al…
Open star cluster: formation, parameters, membership and importance
Gireesh C. Joshi
We have been represented the collective information of estimation procedures of parameters of the open clusters and put them together for showing the importance of clusters to unde…
Statistical analysis for precise estimation of structural properties of NGC 1960
Gireesh C. Joshi, R. K. Tyagi
The statistical analysis of gathered of astronomical objects (such as open cluster) are excellent tools to compute its parameters and to constrain the theory of its evolution. Here…
Dynamical properties and search of variable stars: NGC 1960
Gireesh C. Joshi
The total-to-selective extinction RV in the direction of a cluster is found to be 3.12 +/- 0.2 (close to its normal value). We derive the luminosity and mass functions for the clus…
Dynamical Features of Open Star Cluster: DOLIDZE 14
Gireesh C. Joshi, R. K. Tyagi
The radial density profile (RDP) of cluster DOLIDZE 14 provides the radius of 9.8 arcmin, it is based on consideration of first plateau region of RDP. This value is less than the r…
Complex stellar system ESO65SC03: Open cluster or remnant?
Gireesh C. Joshi, Y. C. Joshi, S. Joshi +2
We present a complete spatial and dynamical study of the poorly populated stellar system ESO65SC03. The radial distribution of the system gives a core and cluster radii of 1.10+/-0…
Basic Parameters of Open Star Clusters DOLIDZE 14 and NGC 110 in Infrared bands
Gireesh C. Joshi, Y. C. Joshi, S. Joshi +1
The basic physical parameters of a poorly studied open cluster NGC 110 and an unstudied open cluster DOLIDZE 14 are estimated in the present study using the archival PPMXL and WISE…
