The Accelerating Decline of the Mass Transfer Rate in the Recurrent Nova T Pyxidis
P. Godon, E. M. Sion, R. E. Williams +3
The recurrent nova T Pyxidis has erupted six times since 1890, with its last outburst in 2011, and the relatively short recurrence time between classical nova explosions indicates…
Hubble Space Telescope images of SN 1987A: Evolution of the ejecta and the equatorial ring from 2009 to 2022
Sophie Rosu, Josefin Larsson, Claes Fransson +9
Supernova (SN) 1987A offers a unique opportunity to study how a spatially resolved SN evolves into a young supernova remnant (SNR). We present and analyze Hubble Space Telescope (H…
The matter beyond the ring: the recent evolution of SN 1987A observed by the Hubble Space Telescope
J. Larsson, C. Fransson, D. Alp +14
The nearby SN 1987A offers a spatially resolved view of the evolution of a young supernova remnant. Here we precent recent Hubble Space Telescope imaging observations of SN 1987A,…
Three-dimensional distribution of ejecta in Supernova 1987A at 10 000 days
J. Larsson, C. Fransson, J. Spyromilio +19
Due to its proximity, SN 1987A offers a unique opportunity to directly observe the geometry of a stellar explosion as it unfolds. Here we present spectral and imaging observations…
The Expansion Asymmetry and Age of the Cassiopeia A Supernova Remnant
R. A. Fesen, M. C. Hammell, J. Morse +7
HST ACS images of the young SN remnant Cas A are used to explore the expansion and spatial distribution of its highest velocity debris. Proper motions of over 1800 outlying ejecta…
Hubble Space Telescope WFPC-2 Imaging of Cassiopeia A
Robert A. Fesen, Jon A. Morse, Roger A. Chevalier +4
The young SNR Cassiopeia A was imaged with WFPC-2 through four filters selected to capture the complete velocity range of the remnant's main shell in several important emission lin…
