Two new nova shells associated with V4362 Sagittarii and DO Aquilae

By |2021-07-16T03:45:52+03:00September 21st, 2020|

A classical nova is an eruption on the surface of a white dwarf in an accreting binary system. The material ejected from the white dwarf surface generally forms an axisymmetric shell. The shaping mechanisms of nova shells are probes of the processes that take place at energy scales between planetary nebulae and supernova remnants. We report on the discovery of nova shells surrounding the ...

The shaping mechanisms of nova shells are probes of the processes that take place at energy scales between planetary nebulae and supernova remnants. We report on the discovery of nova shells surrounding the post-nova systems V4362 Sagittarii (1994) and more ...

ARISTARCHOS telescope contributes to the discovery of new exoplanets

By |2021-10-10T23:43:33+03:00April 24th, 2020|

ARISTARCHOS telescope contributes to the discovery of new exoplanets In April 2020, a scientific paper (https://arxiv.org/abs/2004.06622) was published in the Astronomical Journal by an international team of researchers led by Benjamin F. Cooke. The work concerns the discovery of two new exoplanets of the type "Hot Jupiter" (Hot Jupiters) around the stars [...]

Optical Surfaces supplied the National Observatory of Athens with precision lenses for the Aristarchos Telescope

Optical Surfaces supplied the National Observatory of Athens with precision lenses for the Aristarchos Telescope Optical Surfaces supplies wide-field imaging lenses for Aristarchos Telescope The Aristarchos Wide-Field Camera (AWFC) is a new wide-field imager that will be used on the 2.3m Aristarchos telescope at the Helmos Observatory in Greece. It [...]
