Homework Problems

Chuck began the discussion of homework.

* Multi-dimensional models for X-ray bursts. --> Connects nuclear experiment directly to astrophysical observer, the most distant line this community needs to cross. HS suggests the nuclear physics remains uncertain for multi-dimensional model, and therefore must pinned down.
* Lots of phenomenology from many different angles (define? what's an angle? - crust cooling, X-ray bursts, and code-to-code comparisons of X-ray bursts. BENCHMARK CASES with identical physics. This will be important with phase plots of NS mass and radius, with different constraints from different phenomena, one wants to be sure that the inputs at the microphysical level are identical.
*FYI: At Michael Smith's repository at nucastrodata.org, the whole community has access to the same primary dataset -- this is intended to act as a benchmark.
* FYIDuncan Galloway's X-ray burst lightcurve repository is a resource for the modeling community.
* Modelling the crust: is it amorphous or crystaline, and do magnetic field evolution affect the the crust. A model of the magnetic field evolution with amorphous conductivity, to see if the crust blows up.
* Make magnetic field evolution models a community resource.
* FYI: European Compstar will provide codes for students for neutron structures, NS rotation, supernova hydrodynamical codes.
* FYI: JINA has a series of schools, dedicated to giving away R-matrix code to analyse reaction codes; some network codes; shell model.
* Wiki for this conference.
* Who are all these people? What do they do? How do I know who does what? It seems important to see the expertise in the field in a plainer way.
* The Wasserman Question: Where are the condensed matter people in all this? For example, they have been working with rotation in superfluid 3He for some time, they must be able to inform our understanding of rotation in neutron stars. We need to do outreach to condensed matter physicists, who study superfluidity and strong magnetic fields in matter, because they were not represented at this workshop.
* Gravitational work will continue to grow in importance to neutron stars. We should be embedding them with us, as soon as possible.

  1. I'd like to thank the organizers for such a great conference. But there is one message I want Bob to take home. There is one good "chinese" restaurant in Santa Fe. It is called "Thai" Cafe. Thanks to Michael Smith, I got the chance to enjoy my last dinner there. Don't get misled by the name, it is a full size restaurant. It is a good choice if you like genuine chinese good. Have a good trip back home to everybody.

  2. Just registered at reddit.com. It is pretty easy, thanks, Bob. For new users, just click the top left tab "My Reddits" to subscribe or unsubscribe your list of topics, then you are ready to go. Remember to add the reddit of "neutron star structure" that Bob created (you may have to use the search function to find it). Homework for Bob: send an email to everybody at least the participants of this meeting about reddit (some left early and missed your wonderful idea).

  3. With respect to Reddit; searching for "neutron star structure" didn't give me any hits. Find our topic through searching for "neutronstarstructure".
    Cheers,
    Craig

    PS--And many thanks to the organizers!
