Syllabus:
Focus of the research:
Today, we know of more than 5000 extrasolar planets (exoplanets). Smaller objects such as exoasteroids and exoplanets have been discovered too. Most of them are transiting their host stars and their transits have nice symmetric shape and are stable. This is similar to eclipses in eclipsing binaries. However, there are objects with anomalous, asymmetric, and variable transits or eclipses. These will be of our main interest. This field of research is evolving quickly opening new possibilities, surprises and challenges. That is why objectives of the thesis may shift according the current situation, availability of data, as well as interests and activity of the student.
Objectives:
-disintegrating exoplanets or “exo”bodies on close orbits around their parent stars (photometry, simulations)
-eclipsing stellar systems with dark dusty disks – a cradle for planets (photometry and modelling of spectra and lightcurves),
-reflection effect and albedo in interacting binaries and exoplanets (photometry and modelling)
Requirements:
knowledge of English language, basics of Astronomy and Astrophysics.
Welcomed experience: programming (Fortran, Python,…), Linux operating system,
Research field:
Extrasolar planets, brown dwarfs, and low mass stars, Binary and multiple stellar systems
Literature:
Heng, K. 2017, Exoplanetary Atmospheres, Princeton Univ. Press
