Special Issue Information
Dear Colleagues,
Type Ia supernovae (SNe Ia) play a pivotal role in astrophysics. Their standardised light curves enabled the measuring the Universe's expansion rate (Gruber Prize, 2009) and acceleration (Nobel Prize, 2011). As primary producers of iron peak and alpha elements, they shape galactic evolution and serve as key laboratories for thermonuclear explosion physics. However, the origins of SNe Ia remain elusive, with ongoing debates surrounding the nature of the donor star, evolutionary pathways, and explosion mechanisms—challenges further underscored by the discovery of peculiar SNe Ia.
Observations across different timescales offer unique insights into SNe Ia. Early time data reveal outer ejecta composition and possible interactions with a companion star, while late time observations probe the explosion’s deepest regions. Elements like manganese trace progenitor properties, and remnants of historical SNe Ia offer clues through their evolving structures. The study of SNe Ia is diverse, combining numerical modelling, astronomical observations, lab experiments, and nuclear reaction analysis to unravel their mysteries.
This Special Issue aims to bring together contributions for a discussion on the observational and theoretical aspects of Type Ia supernovae. We invite contributions covering a wide range of topics, including stellar structure modelling, nucleosynthesis calculations, spectroscopic observations, radiative transfer simulations, galactic chemical evolution, and experimental nuclear astrophysics.
This Special Issue aims to present the state of the art in these research fields and explore future directions. We welcome submissions on all relevant topics, including, but not limited to, those mentioned above.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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-blind 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.
