Özet
New features integrated into the open-source Doppler imaging code SpotDIPy were introduced, with an application performed on the young solar-like star V1358 Ori. A three-temperature approximation was adapted to the SpotDIPy code to reconstruct regions on the stellar surface that are both cooler and hotter than the photosphere. Additionally, the code was updated to enable simultaneous solutions of both spectroscopic and photometric data. The code has been improved both in terms of performance and user interface. The high-resolution spectra and the TESS light curve of V1358 Ori were simultaneously modeled for the first time using the new version of SpotDIPy, resulting in the surface brightness distribution of the star.
