The Extremely Large Telescope Interferometer
Francisco Prada, Enrique Perez, Sergio Fernandez-Acosta +2
The ELTI concept capitalizes on recent breakthroughs in large-format SPAD (Single-Photon Avalanche Diode) imaging sensors, combining them with the unprecedented collecting area and…
Observations of Binary Stars with the 1.3-m Devasthal Fast Optical Telescope Using Speckle Interferometry: An Attempt
Km Nitu Rai, Arjun Dawn, Neelam Panwar +3
We present a feasibility study exploring the implementation of optical interferometry and speckle techniques with the 1.3-m Devasthal Fast Optical Telescope (DFOT) at ARIES, which…
Stellar Multiplicity via Speckle Interferometry with the 3.6 m Devasthal Optical Telescope
Km Nitu Rai, Neelam Panwar, Jeewan C Pandey +3
Conventional ground-based optical telescopes, even those with large apertures, primarily observe stars, close binaries, and multiple systems as unresolved point sources through pho…
Radial Pulsations in Polaris: A Secondary Science Application of Cherenkov Telescopes via Intensity Interferometry
Km Nitu Rai, Prasenjit Saha, Subrata Sarangi
Ground-based Cherenkov telescopes, although typically inoperative during moonlit nights for gamma-ray observations, offer a valuable opportunity for secondary scientific applicatio…
Radius measurement in binary stars: simulations of intensity interferometry
Km Nitu Rai, Soumen Basak, Prasenjit Saha
Mass and radius measurements of stars are important inputs for models of stellar structure. Binary stars are of particular interest in this regard, because astrometry and spectrosc…
