Publications and resources

• List of recent solar publications with links to Postscript versions

• List of recent stellar publications with links to Postscript versions

• Publications listed by the Astrophysics Data System (ADS) (but not the couple on asteroids, and there are some others under S. White)

• HTML version of the Powerpoint talk given at the Noordwijk meeting on Solar and Stellar Coronae: The Radio Sun. You should set your browser to at least 900 pixels wide and 900 deep: there should be 3 windows (slides, navigation, notes) plus navigation arrows at the bottom below the Notes window. Fonts may not appear correctly in Unix or Linux because the PowerPoint fonts are not available: you can make it look better by setting your browser to use the fonts you specify, not the document fonts.

• A drop-in version of the SolarSoft GOES toolbench widget that allows a choice of abundances in calculating the temperature and emission measure, and uses up-to-date CHIANTI spectral models, is described in the Solar Physics paper by White, Thomas, Schwartz, 2005. Updated responses are available in SolarSoft (you want goes_chianti_tem.pro, goes_get_chianti_em.pro and goes_get_chianti_temp.pro, or just use the goes widget in SolarSoft). Current for GOES 14 (assumes GOES 15 is identical for the moment).

• There are now IDL routines to read and plot dynamic radio spectra of solar radio bursts from the Air Force RSTN network of patrol telescopes in the NGDC package of Solarsoft that are versions of my original routines, read_rstn_srs.pro and plot_rstn_srs.pro, improved by Sam Freeland (the Solarsoft versions use UNIX sockets instead of wget) and made compatible with Solarsoft practices. The plotting routine needs the NASA/Goddard and JHUAPL libraries of IDL routines, partially included within Solarsoft (gen/idl/fund_lib). Other custom routines are included in the file. Let me know if there are problems. The routine will download data that Helen Coffey thankfully has worked hard to obtain for NGDC (the download might use a mirror at LMSAL in Solarsoft) but it is best for you to check first that data are available at ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/SOLAR_RADIO/.

• Frequency-Agile Solar Radiotelescope (FASR) project home page at NJIT.

FASR is a solar-dedicated radio telescope which will combine imaging capability better than the VLA with high spectral resolution. It will operate in the core frequency range 0.3-30 GHz, and will be a multi-purpose instrument capable of studying virtually every phenomenon in the solar atmophere, with particular emphasis on electron acceleration in solar flares and magnetic fields in the corona and in solar flare energy release regions.

The concept has now been recommended amongst the top scientific priorities for medium-sized projects by the current NRC Astronomy and Astrophysics Survey Committee (the "McKee-Taylor decadal report"): both brief and fuller (9 MB file) descriptions of the project are available.

In addition, a PDF version of the FASR poster is available here.
