Multiband Photometric and Spectroscopic Analysis of HV Cnc

In this paper, radial velocity and VI-and JHK(S)- (Two Micron All Sky Survey) band photometric data of the detached system HV Cnc have been analyzed. The primary component of HV Cnc, which is a member of the M67 cluster, is suspected to be either a blue straggler or turn-off star. The system is a single-lined spectroscopic binary and its light curve shows a total eclipse. Spectroscopic observations of the system revealed the third component, which shows contribution to the total light of the system. Light curve and radial velocity data have been analyzed using the Wilson-Devinney (W-D) code and JHK(S) filter definitions computed for the W-D code in this work. Our analysis shows that the mass and radius of the primary and secondary components are 1.31 M-circle dot, 0.52 M-circle dot, 1.87 R-circle dot, and 0.48 R-circle dot, respectively. All results are compared with previously published literature values and discussed.
