Query: A statistical search for Star-Planet Interaction in the UltraViolet
  using GALEX   Most (~82%) of the over 4000 confirmed exoplanets known today orbit very
close to their host stars, within 0.5 au. Planets at such small orbital
distances can result in significant interactions with their host stars, which
can induce increased activity levels in them. In this work, we have searched
for statistical evidence for Star-Planet Interactions (SPI) in the ultraviolet
(UV) using the largest sample of 1355 GALEX detected host stars with confirmed
exoplanets and making use of the improved host star parameters from Gaia DR2.
From our analysis, we do not find any significant correlation between the UV
activity of the host stars and their planetary properties. We further compared
the UV properties of planet host stars to that of chromospherically active
stars from the RAVE survey. Our results indicate that the enhancement in
chromospheric activity of host stars due to star-planet interactions may not be
significant enough to reflect in their near and far UV broad band flux.
