Spectro-polarimetry of HAbitable Planet Earth (SHAPE) on Chandrayaan-3: Instrument characteristics, calibration and onboard performance
Bhavesh Jaiswal, Swapnil Singh, Ravishankar B T +20
The orbiter of the Chandrayaan-3 mission of the Indian Space Research Organisation (ISRO) carries an experimental payload called SHAPE (Spectro-polarimetry of HAbitable Planet Eart…
Shaping SHAPE - A spectro-polarimeter onboard Chandrayaan-3 to observe Earth as an Exoplanet
Anuj Nandi, Swapnil Singh, Bhavesh Jaiswal +33
Spectro-polarimetry of HAbitable Planet Earth (SHAPE) is an experimental instrument onboard the Propulsion Module (Orbiter) of the Chandrayaan-3 mission, designed to perform disc-i…
Observability of radio reflections from exoplanet ionospheres with next generation radio telescopes
Bhavesh Jaiswal, Nirupam Roy
Much has been learned about exoplanets and their atmospheres in the last three decades with the help of highly sensitive optical telescopes. Limited observations using X-ray telesc…
SHAPE -- A Spectro-Polarimeter Onboard Propulsion Module of Chandrayaan-3 Mission
Anuj Nandi, Swapnil Singh, Bhavesh Jaiswal +31
SHAPE (Spectro-polarimetry of HAbitable Planet Earth) is an experiment onboard the Chandrayaan-3 Mission, designed to study the spectro-polarimetric signatures of the habitable pla…
Scattering Transparency of Clouds in Exoplanet Transit Spectra
Bhavesh Jaiswal, Tyler D. Robinson
The presence of aerosols in an exoplanet atmosphere can veil the underlying material and can lead to a flat transmission spectrum during primary transit observations. In this work,…
Specular reflections from artificial surfaces as Technosignature
Bhavesh Jaiswal
Direct imaging of exoplanets will allow us to directly observe the planet in reflected light. Such a scenario may eventually allow for the possibility to scan the planetary surface…
AOTF based spectro-polarimeter for observing Earth as an Exoplanet
Bhavesh Jaiswal, Swapnil Singh, Anand Jain +2
Earth is the only known habitable planet and it serves as a testbed to benchmark the observations of temperate and more Earth-like exoplanets. It is required to observe the disc-in…
Concept of an achromatic stellar coronagraph and its application for detecting extrasolar planets
Bhavesh Jaiswal
Imaging the planets that orbit around other stars requires blocking the host star which is usually 8-10 orders of magnitude brighter than the planets. This is achieved with the hel…
