Abstract

Abstract : The field of extrasolar planets has become one of the most lively and vibrant field of research in astrophysics. As is almost always the case in astrophysics, a multi‐wavelength approach is required to fully explore and understand the properties of those planets. Also, X‐ray astronomy plays an important role in this process. The host stars of essentially all extrasolar planets are (sometimes very vigorous) X‐ray emitters, which can severely impact on the outer atmospheric layers of their planets. Furthermore, the close proximity between host stars and planets in the case of close‐in "Hot Jupiters" may lead to magnetic or tidal interactions with observable consequences at X‐ray wavelengths. I will address these issues and discuss how XMM‐Newton can be used to advance the field.
