The chemical fingerprint of the Gaia BH3 system. Evidence for early cluster enrichment from the analysis of 51 elements
Gregory Vanden Broeck, Thibault Merle, Nhat Tan Mai +5
The Gaia BH3 system hosts the most massive known stellar-origin black hole and a low-mass metal-poor companion whose chemical composition may constrain early explosive nucleosynthe…

How does the solar chromospheric activity look like under different inclination angles?
G. Vanden Broeck, S. Bechet, G. Rauw +1
Chromospheric plages are distributed between mid-latitude and the Equator and never close to the Poles. Therefore, we suspect that the inclination angle of the solar rotation axis…

Relationship between TIGRE solar S-index and USET Ca II K full disk images
G. Vanden Broeck, S. Bechet, F. Clette +3
Full disk observations of the solar chromosphere in the Ca II K line represent a valuable dataset for studies of solar magnetic activity. The S-index is widely used to investigate…
