Discovery of extended main sequence turn offs in Galactic open clusters
A. F. Marino, A. P. Milone, L. Casagrande +5
By far, the color-magnitude diagrams (CMDs) of Galactic open clusters have been considered proto-types of single stellar populations. By using photometry in ultraviolet and optical…
The Mira-based distance to the Galactic centre
Wenzer Qin, David M. Nataf, Nadia Zakamska +2
Mira variables are useful distance indicators, due to their high luminosities and well-defined period-luminosity relation. We select 1863 Miras from SAAO and MACHO observations to…
The Solar Twin Planet Search: The age - chromospheric activity relation
Diego Lorenzo-Oliveira, Fabrício C. Freitas, Jorge Meléndez +8
It is well known that the magnetic activity of solar type stars decreases with age, but it is widely debated in the literature whether there is a smooth decline or if there is an e…
On the use of Gaia magnitudes and new tables of bolometric corrections
Luca Casagrande, Don A. VandenBerg
The availability of reliable bolometric corrections and reddening estimates, rather than the quality of parallaxes will be one of the main limiting factors in determining the lumin…
Interferometric diameters of five evolved intermediate-mass planet-hosting stars measured with PAVO at the CHARA Array
T. R. White, D. Huber, A. W. Mann +8
Debate over the planet occurrence rates around intermediate-mass stars has hinged on the accurate determination of masses of evolved stars, and has been exacerbated by a paucity of…
The GALAH Survey: Stellar streams and how stellar velocity distributions vary with Galactic longitude, hemisphere and metallicity
Alice C. Quillen, Gayandhi De Silva, Sanjib Sharma +30
Using GALAH survey data of nearby stars, we look at how structure in the planar (u,v) velocity distribution depends on metallicity and on viewing direction within the Galaxy. In ne…
