Mid-infrared imaging of Supernova 1987A
Mikako Matsuura, Roger Wesson, Richard G. Arendt +9
At a distance of 50 kpc, Supernova 1987A is an ideal target to study how a young supernova (SN) evolves in time. Its equatorial ring, filled with material expelled from the progeni…
SOFIA mid-infrared observations of Supernova 1987A in 2016 --- forward shocks and possible dust re-formation in the post-shocked region?
Mikako Matsuura, James M. De Buizer, Richard G. Arendt +10
The equatorial ring of Supernova (SN) 1987A has been exposed to forward shocks from the SN blast wave, and it has been suggested that these forward shocks have been causing on-goin…
PESSTO : survey description and products from the first data release by the Public ESO Spectroscopic Survey of Transient Objects
S. J. Smartt, S. Valenti, M. Fraser +99
The Public European Southern Observatory Spectroscopic Survey of Transient Objects (PESSTO) began as a public spectroscopic survey in April 2012. We describe the data reduction str…
X-ray illumination of the ejecta of Supernova 1987A
J. Larsson, C. Fransson, G. Östlin +25
We present the late-time optical light curve of the ejecta of SN 1987A measured from HST imaging observations spanning the past 17 years. We find that the flux from the ejecta decl…
Abundances and physical parameters for stars in the open clusters NGC 5822 and IC 4756
G. Pace, J. Danziger, G. Carraro +5
Classical chemical analyses may be affected by systematic errors that would cause observed abundance differences between dwarfs and giants. For some elements, however, the abundanc…
An investigation of chromospheric activity spanning the Vaughan--Preston gap: impact on stellar ages
G. Pace, J. Melendez, L. Pasquini +5
Chromospheric activity is widely used as an age indicator for solar-type stars based on the early evidence that there is a smooth evolution from young and active to old and inactiv…
