Galaxy and Mass Assembly (GAMA): Morphological transformation of galaxies across the green valley
M. N. Bremer, S. Phillipps, L. S. Kelvin +13
We explore constraints on the joint photometric and morphological evolution of typical low redshift galaxies as they move from the blue cloud through the green valley and onto the…
SN 2016coi/ASASSN-16fp: An example of residual helium in a type Ic supernova?
S. J. Prentice, C. Ashall, P. A. Mazzali +35
The optical observations of Ic-4 supernova (SN) 2016coi/ASASSN-16fp, from to days after explosion, are presented along with analysis of its physical properties.…
The distance to the LMC cluster NGC 1866 and the surrounding field
M. Salaris, S. Percival, E. Brocato +2
We use the Main Sequence stars in the LMC cluster NGC 1866 and of Red Clump stars in the local field to obtain two independent estimates of the LMC distance. We apply an empirical…
Chemical abundance anticorrelations in globular cluster stars: The effect on cluster integrated spectra
P. Coelho, S. Percival, M. Salaris
It is widely accepted that individual Galactic globular clusters harbor two coeval generations of stars, the first one born with the `standard' -enhanced metal mixture observed…
Photometric and spectroscopic observations, and abundance tomography modelling of the type Ia supernova SN 2014J located in M82
C. Ashall, P. Mazzali, D. Bersier +5
Spectroscopic and photometric observations of the nearby Type Ia Supernova (SN Ia) SN 2014J are presented. Spectroscopic observations were taken -8 to +10 d relative to B-band maxi…
A large stellar evolution database for population synthesis studies. V. Stellar models and isochrones with CNONa abundance anticorrelations
A. Pietrinferni, S. Cassisi, M. Salaris +2
We present a new grid of stellar models and isochrones for old stellar populations, covering a large range of [Fe/H] values, for an heavy element mixture characterized by CNONa abu…
