SIMBAD data

GSC 03089-00929 is a magnitude 12 star located approximately 757 light-years away in the constellation of Hercules. This star is a G type main sequence star that is similar to but slightly cooler than the Sun. [3] This star is identified in SIMBAD as a variable star per the 1SWASP survey. [7]

Contents

The star GSC 03089-00929 is named Pipoltr. The name was selected in the NameExoWorlds campaign by Liechtenstein, during the 100th anniversary of the IAU. In the local dialect of Triesenberg, Pipoltr is a bright and visible butterfly. [8] [9]

Planetary system

In 2007 the TrES program found exoplanet TrES-3b, later named Umbäässa, orbiting this star by using the transit method. [10]

The transit timing variation analysis did not reveal any additional planets in the system as of 2020, [11] and the physical mechanism underlying transit timing variations remains unexplained as in 2022. [12]

HD 208487 is a star with an orbiting exoplanet in the constellation of Grus. Based on parallax measurements, it is located at a distance of 146.5 light years from the Sun. The absolute magnitude of HD 208487 is 4.26, but at that distance the apparent visual magnitude is 7.47, which is too faint to be viewed with the naked eye. The system is drifting further away with a radial velocity of 5.6 km/s. It is a member of the thin disk population.

HD 45350 is a solar analog star with an exoplanetary companion in the northern constellation of Auriga. It has an apparent visual magnitude of 7.89, which means it is an 8th magnitude star that is too dim to be readily visible to the naked eye. The system is located at a distance of 153 light-years from the Sun based on parallax measurements, but is drifting closer with a radial velocity of −21 km/s.
