VizieR Online Data Catalog: Tomography of Betelgeuse (Jadlovsky+, 2024)
Abstract
We present high-resolution echelle spectra of Betelgeuse taken with STELLA echelle spectrograph (SES) operated by AIP. The extensive time series consists of about 2800 spectra (6000 exposures in total) obtained during the past 15 years. The data were reduced using the IRAF-based pipeline SESDR in its version 4.0 (Weber et al. 2008, 2012). Tomographic method was used to create masks representing 5 distinct layers of photosphere. Radial velocities (RV) were determined by cross-correlating the masks with the observed spectra.
