Observing Supernova 1987A with the Refurbished Hubble Space Telescope
Kevin France, Richard McCray, Kevin Heng +18
Observations with the Hubble Space Telescope (HST), conducted since 1990, now offer an unprecedented glimpse into fast astrophysical shocks in the young remnant of supernova 1987A.…
Spectral evolution and polarization of variable structures in the pulsar wind nebula of PSR B0540-69.3
N. Lundqvist, P. Lundqvist, C. -I. Björnsson +4
We present high spatial resolution optical imaging and polarization observations of the PSR B0540-69.3 and its highly dynamical pulsar wind nebula (PWN) performed with HST, and com…
Abundances and density structure of the inner circumstellar ring around SN 1987A
Seppo Mattila, Peter Lundqvist, Per Groeningsson +4
We present optical spectroscopic data of the inner circumstellar ring around SN 1987A from the Anglo-Australian Telescope (AAT) and the Very Large Telescope (VLT) between ~1400 and…
