Abstract:
We report the confirmation and characterization of TOI-1295 b,
TOI-2580 b, TOI-6016 b, and TOI-6130 b, four hot Jupiter-type
exoplanets initially detected by TESS. 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 and
performed precise mass measurements. All four planets are 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, and 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 fit well
with the current models. These four planets belong to the first
planets confirmed with MaHPS data and show the ability of the
spectrograph to detect planets around fainter stars as faint as V=12.
