Evolutionary and pulsation properties of Type II Cepheids
G. Bono, V. F. Braga, G. Fiorentino +7
We discuss the observed pulsation properties of Type II Cepheids (TIICs) in the Galaxy and Magellanic Clouds. The period (P) distributions, luminosity amplitudes and population rat…
Digging for relics of the past: the ancient and obscured bulge globular cluster NGC6256
Mario Cadelano, Sara Saracino, Emanuele Dalessandro +5
We used a set of moderately-deep and high-resolution optical observations obtained with the Hubble Space Telescope to investigate the properties of the stellar population in the he…
The Aarhus red giants challenge II. Stellar oscillations in the red giant branch phase
J. Christensen-Dalsgaard, V. Silva Aguirre, S. Cassisi +23
Context. The large quantity of high-quality asteroseismic data that obtained from space-based photometric missions and the accuracy of the resulting frequencies motivate a careful…
The Aarhus Red Giants Challenge I: Stellar structures in the red giant branch phase
V. Silva Aguirre, J. Christensen-Dalsgaard, S. Cassisi +23
(Abridged). We introduce the Aarhus Red Giants Challenge, a series of detailed comparisons between widely used stellar evolution and oscillation codes aiming at establishing the mi…
Spectroscopic detection of multiple populations in the ~2 Gyr old cluster Hodge 6 in the LMC
K. Hollyhead, S. Martocchia, C. Lardo +8
We report the spectroscopic discovery of abundance spreads (i.e. multiple populations) in the ~2 Gyr old cluster in the LMC, Hodge 6. We use low resolution VLT FORS2 spectra of 15…
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…
