Final fate of low-mass stars: Hic Sunt Leones
We plan to investigate the final evolutionary phases of low-mass stars in Globular Clusters, namely White Dwarfs and the Zoo of binary systems.
Canonical Evolutionary Phases
Iben’s (+ many others) legacy
Exotic objects are in the corner !!!!
XVII - Terra Australis Incognita!!
Omega Centauri: the goldmine
He WDs
M=0.3 Mo H-reignitionCNO flashes
Similar evolutionary times for He WDs & Extreme HBsBut significantly longer than
CO WDs!!
Zoo of binary systems
Verbunt & Lewin (2004)Kong et al. 2006 (NGC288)
• Deep photometry (Run A): I~30 1h with S/N~5
K~29 2h with S/N~3
• Fast Photometry (Run B): I~26 180 sec with S/N~50
J~26 300 sec with S/N~30Run MP Mode AO T. FOV Pixel Notes
A - Imaging LTAO 2n 5’ 10 0.8-2.2 µm I & K
B - Imaging LTAO 1n 5’ 10 0.8-1.2 µm I & J
