WASP-60b
The star was named Morava in 2019 by Serbian amateur astronomers as part of the NameExoWorlds contest, after the Morava River in Serbia.
A multiplicity survey in 2015 did not detect any stellar companions to WASP-60.
Planetary system
In 2012 a transiting hot Jupiter planet b was detected on a tight, circular orbit. The planet was named Vlasina by Serbian astronomers in December 2019, after the Vlasina River, a tributary of the Morava.
Its equilibrium temperature is 1479±35 K.
Measurement of the Rossiter–McLaughlin effect in 2018 revealed WASP-60b is on a retrograde orbit relative to the equatorial plane of the star, orbital obliquity equal to 129±17°.
