Astronomers discover a highly inflated sub-Saturn extrasolar planet

An international team of astronomers led by Joshua Pepper of the Lehigh University in Bethlehem, Pennsylvania,
has detected an extremely inflated sub-Saturn exoplanet orbiting a bright subgiant star. The newly discovered
alien world is one of the most inflated, least dense planets known to date. The findings were presented in
a paper published July 6 on arXiv.org.
The team used the Kilodegree Extremely Little Telescope (KELT) to observe a bright subgiant star named HD 93396
(KELT-11), which is located some 320 light years away. They were looking for transit signals indicating the presence
of a planet circling this distant star. KELT was chosen for this job as it can observe stars generally brighter than
those observed by other ground-based surveys.
