Exoplanets

Exoplanet (extrasolar planet) is a planet outside Solar system. The first exoplanet Gamma Cephei Ab (also named Tadmor) was detected in 1988 (confirmed in 2003). The first confirmation of exoplanet was in 1992 (which was detected in 1988), this exoplanet is PSR 1257+12 (also named Lich).

Exoplanet research is a new field of astrophysics, astronomy and planetary science, which invokes most modern techniques of observation and numerical modeling.

The most established family of exoplanets detection methods are based on comparison of in-transit and out-of-transit spectra (see figure). So with the great precision we can know not only about their presence, but also about their atmospheres composition.

Thus, the results of exoplanet research have prospects for the development of other fields such as astrobiology, cosmology, and technology.

Since exoplanet research is a developing field, there are few sufficiently accurate modeling methods, while they often neglect observational data, use simplified models, and also it’s hard to integrate them into other projects. Astrea project was created to provide the opportunity to use the most complex and sophisticated models of chemical elements, real observational spectra and the most fundamental form of flexible interaction with other software products (such as most advanced exoplanet atmosphere magnetohydrodynamics code Exo3D).
