Orbiting a binary: SPHERE characterisation of the HD 284149 system
Mariangela Bonavita, V. D'Orazi, D. Mesa +52
In this paper we present the results of the SPHERE observation of the HD 284149 system, aimed at a more detailed characterisation of both the primary and its brown dwarf companion.…
NGC 6752 AGB Stars Revisited: I. Improved AGB temperatures remove apparent overionisation of Fe I
S. W. Campbell, B. T. MacLean, V. D'Orazi +5
A recent study reported a strong apparent depression of Fe I, relative to Fe II, in the AGB stars of NGC 6752. This depression is much greater than that expected from the neglect o…
An extreme paucity of second population AGB stars in the normal globular cluster M4
B. T. MacLean, S. W. Campbell, G. M. De Silva +4
Galactic Globular clusters (GCs) are now known to harbour multiple stellar populations, which are chemically distinct in many light element abundances. It is becoming increasingly…
The Asymptotic Giant Branches of GCs: Selective Entry Only
S. W. Campbell, V. D'Orazi, T. N. Constantino +7
The handful of available observations of AGB stars in Galactic Globular Clusters suggest that the GC AGB populations are dominated by cyanogen-weak stars. This contrasts strongly w…
