Fundamental Processes in Neutron Stars and Supernovae

Dear Colleagues,

In the last few years, we have made spectacular progress in our understanding of the physics of Neutron Stars and Supernovae, both from observations and from theory. Our understanding of these compact objects amply relies on our knowledge of the microphysics of the fundamental processes that determine their structure and dynamics. In this respect, both observations and theoretical analysis are crucial to improving our capacity to predict the rate and dynamics of each one of these processes, as well as to discovering new phenomena. The aim of this Special Issue of Universe is to report on the latest developments and to stimulate new ones in the field. These topics include but are not limited to the following:

• transport in neutron stars and neutron star mergers;
• neutrino trapping and emission in neutron stars;
• neutrino emissions and dynamics in supernovae;
• nucleosynthesis in supernovae simulations;
• neutron star cooling;
• gravitational waves from neutron star mergers;
• gravitational waves from neutron star oscillations;
• magnetic field structure and dynamics in neutron star formation;
• and onset of quark matter in neutron stars

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
