Adding TESS to CR\'EME. Light curves and masses of 300+ eclipsing binaries

TL;DR

This paper reports on the integration of TESS space photometry with the CR'EME project, providing light curves and mass estimates for over 300 eclipsing binaries, enhancing the understanding of these systems.

Contribution

It introduces the combination of high-resolution spectroscopy with TESS photometry for a large sample of eclipsing binaries, expanding the dataset and analysis capabilities.

Findings

Masses of 325 double-lined eclipsing binaries estimated.

Photometric data for over 330 targets collected from TESS.

Ongoing comprehensive analysis of eclipsing binary systems.

Abstract

The Comprehensive Research with Echelles on the Most interesting Eclipsing binaries (CR\'EME) projects was aimed to collect high-resolutions spectra of about 380 detached eclipsing binaries (DEBs), which mostly do not have literature RV data. From this vast observational material we were able to estimate masses of components of 325 double-lined system. Since the launch of the TESS mission we have been collecting 2-min cadence photometry for the CR\'EME targets through successful GI proposals. As by Sector 85, we obtained data for $>$330 of them. We are thus now in the process of comprehensively analyzing our targets. This paper presents the recent status of the CR\'EME project and its space photometry counterpart, and describes several sub-projects within CR\'EME that focus on specific classes of targets.
