Pulsations along the Asymptotic Giant Branch (AGB): a global view
Pierre Darriulat, Pham Thi Tuyet Nhung, Do Thi Hoai
In three preceding articles, we studied the relation between the light curves of Mira variables and their stellar properties. The analysis was restricted to a sample of stars offer…
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…
From the light curves of Long Period Variables to their evolution along the AGB
Pham Thi Tuyet Nhung, Mai Nhat Tan, Do Thi Hoai +1
A sample of 116 Long Period Variables is studied with the aim to reveal relations between the properties of their light curves and of their evolution along the Asymptotic Giant Bra…
Stellar evolution along the AGB as revealed by the shape of Miras' visual light curves
D. T. Hoai, P. T. Nhung, P. Darriulat +1
A new analysis of a sample of visual light curves of Mira variables is presented. The curves cover the past four decades and are selected from the AAVSO database as including a ver…
Millimetre observations of the S-type AGB star Cygni: variability of the emission of the inner envelope
D. T. Hoai, J. M. Winters, P. T. Nhung +2
New observations are presented of millimetre line emissions of the circumstellar envelope (CSE) of AGB star Cygni using the recently upgraded NOEMA array. Cygni is an S-t…
