Description
Recently, large catalogues of exoplanet and eclipsing binary candidates are reported in the Kepler archival data. In the framework of BINA, we therefore initiated a long-term project "Optical characterization and Radial velocity monitoring with Belgian and Indian Telescopes (ORBIT)" which focuses on ground-based photometric monitoring and high-resolution spectroscopic observations of selected exoplanet candidates and low-mass eclipsing binary candidates using the Indo-Belgian telescopes. We initially focus our study on few bright candidates for which radial velocity monitoring could be possible from the recently mounted high-resolution spectrograph on 2-m Himalayan Chandra Telescope (HCT). Along with planned photometric observations using small-size telescopes at ARIES, Nainital, we aim to determine their physical parameters with a great precision. Having enough sample off such low-mass objects, we aim to understand their mass-radius characteristic which is still debated towards the lower-mass regime. Furthermore, if a transit occurs during the period of spectroscopic observations, it may also help to monitor the Rossiter-McLaughlin effect which plays an important role in the understanding of the characteristics of the secondary star, particularly in the case of a low-mass star or planetary companion.
