This JINA-INT workshop will bring together researchers working on topics related to the thermal evolution of neutron stars, and transient and burst phenomena hosted by accreting and magnetized neutron stars.
The hybrid meeting will involve a small group of in-person attendees at the Institute for Nuclear Theory at the University of Washington, and online participants from around the world.

Title: Radioactive Nuclides in Outer Space
Abstract: Nuclear astrophysics is generally the study of the energy generation in stars and the origins of the chemical elements. In this highly multidisciplinary field, the job of experimental nuclear physicists is to constrain the nuclear reaction rates which are linked with astronomical observables. Observation of the lightest chemical element with no stable isotopes, technetium, in stellar spectra, was the first evidence that nucleosynthesis is an on-going process in our Galaxy.
The mission of CUWiP is to encourage undergraduate women to persist or start a career in physics by proving them with the opportunity to learn about career paths in physics, experience a professional conference, and discuss challenges and concerns. This conference was initiated in 2006 and research data indicate that CUWiP is effective in meeting its goals. It is being supported by in part from the National Science Foundation and the Department of Energy.

Title: Exploring Axion-like Particles with Nearby Supernovae
Our main goal is to connect researchers interested in the origin of isotopes working on presolar grain measurements, stellar chemical abundances, nucleosynthesis, and galactic chemical evolution to understand the origin of the isotopes. This will be a short two-half-day online workshop consisting of invited presentations. We will then organize a series of open online discussion sessions over the rest of the year on focused topics.
Nuclei in the Cosmos is the most important international meeting in the field of nuclear astrophysics. It brings together nuclear experimentalists, nuclear theorists, astronomers, theoretical astrophysicists, cosmo-chemists, and others interested in the scientific questions at the interface of nuclear physics and astrophysics. These questions concern, for example, the origin of the elements in the cosmos and the nuclear reactions that occur in the big bang, in stars, and in stellar explosions.
NIC school is a traditional satellite meeting intended to educate young students and postdocs, motivating them with the most recent progress as well as unresolved quests in nuclear astrophysics. Topics include Astrophysics, Observation, and Nuclear Physics.

(α,n) reactions play a pivotal role in a variety of astrophysical sites and mass regions, and they can help us understand the origin of the elements. Their astrophysical rates are the main nuclear physics uncertainty in the weak r-process (also known as the α-process), which occurs in the neutrino driven ejecta of core-collapse supernovae and can explain the production of the lighter heavy elements, that are observed in metal poor stars. The 22Ne(α,n)25Mg and 13C(α,n)16O reactions are the main neutron sources for the s- and the i-processes.
Embracing the virtual nature of the workshop, the meeting will be broken into three half-day sessions. No parallel sessions are planned. Zoom will be used for the primary presentation of technical content, while substantial breaks are planned where critical informal discussion can take place in Gather.Town. Gather.Town allows us to invite you for a virtual coffee and exciting discussions.
Planned topics of discussion include:
We would like to invite you to participate in an online IReNA sponsored workshop on all things R-matrix that will be held from June 21 - 24, 2021. This meeting will have an abbreviated format and will focus on presentations by young and early career researchers.
The aim of this meeting is to bring together a diverse group of researchers with representatives from experiment and theory who utilize the R-matrix formalism for a variety of purposes.
Talks will span a wide range of topics covering experimental, theoretical, evaluation developments using R-matrix.

Three-dimensional hydrodynamical simulations unravel the evolution of SN 1987A from the explosion to the supernova remnant (Opens in a new window)
Dr. Masaomi Ono
Abstract: Supernova 1987A (SN 1987A) provides a unique opportunity to unravel the evolution of core-collapse supernovae (CCSNe) from the explosions to their supernova remnants (SNRs) thanks to its proximity and youth. Early observation of iron lines has indicated matter mixing during the explosion to convey innermost 56Ni to outer layers. Since the density structure of the progenitor star affects the matter mixing, it provides a hint on the properties of the progenitor star.
Constraining Tidal deformability from finite nuclei data, Bijay Agrawal (Saha Institute of Nuclear Physics) (Opens in a new window)
*Please note that this seminar will take place at 11:00am ET
Saha Institute of Nuclear Physics
The tidal deformability inferred from the Gravitational Waves, which are emitted by merging neutron stars, are instrumental in determining the equation of state (EoS) of dense matter. The importance of the observed finite nuclei properties in unveiling the correlations of the tidal deformability with the key EoS parameters will be discussed.
PAN-CAKE is a free online masterclass for teachers scheduled on March 13 & 14, 12:30-4:00pm ET. Science teachers (from pre-service to veterans) in the US and Canada will learn about world-class scientific research in nuclear astrophysics at MSU’s Facility for Rare Isotope Beams. This is an opportunity to meet scientists and other educators, take a “virtual tour” of a leading rare isotope laboratory, collect tools and demos for your curriculum, and discover the future of research.
