Proto-neutron stars forming a few seconds after core-collapse supernovae are hot and dense environments where hyperons can be efficiently produced by weak...
Protoneutron stars formed during core-collapse supernovae are hot and dense environments that contain a sizable population of muons. If these interact with new...
Supernovae 2016bdu and 2005gl, and their link with SN 2009ip-like transients: another piece of the puzzle
Supernova (SN) 2016bdu is an unusual transient resembling SN 2009ip. SN 2009ip-like events are characterized by a long-lasting phase of erratic variability...
Supernovae and Their Expanding Blast Waves during the Early Evolution of Galactic Globular Clusters
Our arguments deal with the early evolution of Galactic globular clusters and show why only a few of the supernovae (SNe) products were retained within globular...
Supershells as probe particles for the study of the galactic spin orientation
Here we describe a method that can be used to derive, with a high degree of confidence, the direction of the rotation axis of a galaxy. The method is based on...
Supersonic Continuation of the Evershed Flow Outside a Sunspot as Observed with Hinode
We report on the discovery of mostly horizontal field channels just outside sunspot penumbrae (in the so-called "moat" region) that are seen to sustain...
Supersonic Line Broadening and the Gas Dynamical Evolution of Giant HII Regions
We have analyzed high spatial and spectral resolution Hα emission-line TAURUS data on two nearby giant H II regions, NGC 604 and NGC 588. Previous work shows...
Supersonic Line Broadening within Young and Massive Super Star Clusters
The origin of supersonic infrared and radio recombination nebular lines often detected in young and massive superstar clusters is discussed. We suggest that...
Supersonic Magnetic Upflows in Granular Cells Observed with SUNRISE/IMAX
Using the IMaX instrument on board the SUNRISE stratospheric balloon telescope, we have detected extremely shifted polarization signals around the Fe I 5250.217...
