Opening a new window on the southern stars for less money: PAIX the first Antarctica polar mission photometer
2016
In this invited paper, we implement a new way to study the
stellaroscillations, pulsations and their evolutionary properties with long uninterrupted and continuous precision observations over 150 days from the ground, and without the regular interruptions imposed by the earth rotation. PAIX–First Robotic Antarctica Polar Mission– gives a new insight to cope with unresolved
stellarenigma and
stellaroscillation challenges and offers a great opportunity to benefit from an access to the best astronomical site on Earth –DomeC–. The project is made of low cost commercial components, and achieves astrophysical measurement time-series of
stellar physicsfields, challenging photometry from space that shows large gaps in terms of flexibility during the observing runs, the choice of targets, the repair of failures and the inexorable high costs. PAIX has yet more advantages than space missions in observing in UBV RI bands and then collecting unprecedented simultaneous multicolor light curves of several targets. We give a brief history of the Astronomy in Antarctica and describe the first polar robotized mission PAIX and the outcome of
stellar physicsfrom the heart of Antarctica during several
polar nights. We briefly discuss our first results and perspectives on the pulsating stars and its evolution from Antarctica, especially the connection between temporal hydrodynamic phenomena and
cyclic modulations. Finally, we highlight the impact of PAIX on the
stellar physicsstudy and the remaining challenges to successfully accomplish the Universe explorations under extreme conditions.
