| Summary:
We report the confirmation and characterization of four hot Jupiter-type
exoplanets initially detected by TESS: TOI-1295 b, TOI-2580 b, TOI-6016 b, and
TOI-6130 b. Using observations with the high-resolution echelle spectrograph
MaHPS on the 2.1m telescope at Wendelstein Observatory, together with NEID at
Kitt Peak National Observatory and TRES at the Fred Lawrence Whipple
Observatory, we confirmed the planetary nature of these four planet candidates.
We also performed precise mass measurements. All four planets are found to be
hot Jupiters with orbital periods between 2.4 and 4.0 days. The sizes of these
planets range from 1.29 to 1.64 Jupiter radii, while their masses range from
0.6 to 1.5 Jupiter masses. Additionally, we investigated whether there are
signs of other planets in the systems but have found none. Lastly, we compared
the radii of our four objects to the results of an empirical study of radius
inflation and see that all four demonstrate a good fit with the current models.
These four planets belong to the first array of planets confirmed with MaHPS
data, supporting the ability of the spectrograph to detect planets around
fainter stars as faint as V=12.
