23. Observing transiting exoplanets in colors with ASTEP+

Tristan Guillot (OCA)

The ASTEP telescope has begun since 2019 an active program to confirm and monitor long-period transiting exoplanets. Its unique localisation at the Concordia station, Antarctica, allows the observation of targets difficult to observe from other latitudes, in particular when close to the celestial South pole or for long-duration transits. This is ideal to follow-up TESS exoplanetary candidates...

27. Rare Transits Observed by ASTEP from Antarctica

The Transiting Exoplanet Survey Satellite was launched in 2018 to search the sky for planetary candidates. Of the 870+ southern planetary candidates from TESS currently awaiting confirmation, roughly 10% have transit durations longer than five hours; a further third of these have orbital periods longer than 20 days. Systems like these could fall into the sparsely populated parameter space of...

31. The One-meter Polar Large Telescope (PLT) prototype for Concordia

Isabelle Vauglin (CRAL/CNRS - Observatoire de Lyon)

Following the ANGISS 2.5m off-axis telescope project, presented at the AAA-2015 conference, we propose to build a 1m prototype for 2.5m PLT. Such an optical design is based on a common 2.5m off-axis primary mirror delivering two science cases modes: (1) two mirror corrector optimized to a wide FOV (1Deg) for IR survey and (2) one mirror corrector optimized for a narrow FOV for direct exoplanet...

15. Unveiling Our Dynamic Infrared Sky

Mansi Kasliwal (Caltech)

Many astronomical events shine the brightest in the infrared due to atomic opacity, self enshrouding, dust extinction, or low temperature. When we saw the first electromagnetic counterpart to gravitational waves from a binary neutron star merger, it was the rapid reddening due to bound-bound opacity and infrared spectral features that confirmed the synthesis of heavy elements by the r-process....

14. Cryoscope, a technology pathfinder for time domain astronomy in the NIR

Roger Smith (Caltech)

10/09/2021, 12:05

The convergence of many new technologies will soon enable high cadence surveys of the infrared sky for the first time. We describe a pathfinder telescope currently under construction, which will demonstrate imaging over a field of view two orders of magnitude greater than previously achieved in the thermal infrared. The novel optical design not only delivers diffraction limited image...
