cds-question@unistra.frmultiple-starsexoplanetsradial-velocityvisible-astronomyWe 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=12.2024A&A...692A.220Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/692/A220CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/692/A220https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/692/A220http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/692/A220https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/692/A220https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/692/A220http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/692/A220GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/692/A220/toi1295RV-Values of TOI-1295 (without observations taken during transits)recnoRecord number assigned by the VizieR team.
