The Discovery of lambda Bootis Stars -- The Southern Survey II
Simon J. Murphy, Richard O. Gray, Christopher J. Corbally +3
The Boo stars are chemically peculiar A-type stars whose abundance anomalies are associated with the accretion of metal-poor material. We searched for Boo stars in the sout…
Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
Variable Stars in M13. III. The Cepheid Variables and their Relation to Evolutionary Changes in Metal-poor BL Her Stars
Wayne Osborn, Grzegorz Kopacki, Horace A. Smith +3
New CCD photometry has been combined with published and unpublished earlier observations to study the three Cepheid variables in M13: V1, V2 and V6. The light curve characteristics…
Large amplitude change in spot-induced rotational modulation of the Kepler Ap star KIC 2569073
Jason A. Drury, Simon J. Murphy, Aliz Derekas +9
An investigation of the 200 200 pixel 'superstamp' images of the centres of the open clusters NGC 6791 and NGC 6819 allows for the identification and study of many variabl…
Little Bear's Pulsating Stars: Variable Star Census of dSph UMi Galaxy
K. Kinemuchi, E. Jeffery, C. Kuehn +2
Recent observations and a photometric search for variable stars in the Ursa Minor dwarf spheroidal galaxy (UMi dSph) are presented. Our observations were taken at Apache Point Obse…
Towards 21st Century Stellar Models: Star Clusters, Supercomputing, and Asteroseismology
S. W. Campbell, T. N. Constantino, V. D'Orazi +8
Stellar models provide a vital basis for many aspects of astronomy and astrophysics. Recent advances in observational astronomy -- through asteroseismology, precision photometry, h…
