Non-Sinusoidal Transit Timing Variations for the Exoplanet HAT-P-12b
Devesh P. Sariya, Ing-Guey Jiang, Li-Hsin Su +14
Considering the importance of investigating the transit timing variations (TTVs) of transiting exoplanets, we present a follow-up study of HAT-P-12b. We include six new light curve…
A comprehensive analysis of NGC 2158 in Gaia era: photometric parameters, apex and orbit
Devesh P. Sariya, Ing-Guey Jiang, M. D. Sizova +7
We present an investigation of NGC 2158 using Gaia-DR2 data. We identified 800 most likely cluster members with membership probability higher than 90%. The mean proper motions of t…
Optimal angle bounds for quadrilateral meshes
Christopher J. Bishop
We show that any simple planar n-gon can be meshed in linear time by quadrilaterals with all new angles bounded between and degrees.
An investigation of poorly studied open cluster NGC 4337 using multi-color photometric and Gaia DR2 astrometric data
D. Bisht, W. H. Elsanhoury, Qingfeng Zhu +5
We present a comprehensive analysis (photometric and kinematical) of poorly studied open cluster NGC 4337 using 2MASS, WISE, APASS, and Gaia~DR2 database. By determining the member…
A Comprehensive study of open clusters Czernik 14, Haffner 14, Haffner 17 and King 10 using multicolour photometry and Gaia DR2 astrometry
D. Bisht, Qingfeng Zhu, R. K. S. Yadav +2
This paper presents an investigation on the four open clusters Czernik 14, Haffner 14, Haffner 17 and King 10 located near the Perseus arm of Milky Way Galaxy using Gaia DR2, 2MASS…
A Search for variable stars in the four open star clusters
Alok Durgapal, Geeta Rangwal, D. Bisht +3
We present a CCD photometric survey for the search of variable stars in four open clusters namely Berkeley 69, King 5, King 7, and Berkeley 20. The time series observations were ca…
Study of open cluster King 13 using CCD VI, 2MASS and Gaia DR2 Astrometry
Alok Durgapal, D Bisht, Geeta Rangwal +2
In this paper, we present astrophysical parameters of the open cluster King 13 based on the VI CCD and 2MASS JHKs photometric data. This is a poorly studied cluster, for which new…
