THE EVLA VISION: STARS ON AND OFF THE MAIN SEQUENCE

26-28 May 2009, Socorro, New Mexico, USA

Scientific Rationale

The VLA revolutionized the field of stellar radio astronomy, with detections across almost the whole Hertzsprung-Russell diagram, and the opening of entire new fields of research. The EVLA promises similarly impressive advances, with massive improvements in sensitivity, instantaneous bandwidth, frequency coverage, spectral capability, and transient source response. The object of this conference is to explore what this will mean for studies of stars. Some examples include:
  • New source populations: e.g., first detections of solar-type radio emission from other stars; census of pulsars in the Galactic Center; type I supernovae.
  • Fuller exploration of known populations: e.g., detection of all novae, anywhere in the galaxy; complete census of SNRs in nearby galaxies.
  • Complete coverage of selected individual events: e.g., "cradle to grave" imaging of nearby transients (X-ray binaries, novae, SGRs, ...).
  • Imaging of many galactic sources that we can now only detect: e.g., stellar photospheres.
  • Circumstellar chemistry: e.g., complete coverage of spectral lines from 1 to 50 GHz in stellar outflows
  • Fast & sensitive time response: e.g., explosive events (CVs, novae, XRBs, SNe); stellar radio bursts. The data collected will also be much more interesting, since (1) the higher sensitivity will lead to factor-10 better time resolution; and (2) the EVLA will measure spectral indices, polarizations, rotation measures, and dynamic spectra, in addition to simple flux densities, without any loss of continuum sensitivity.
  • The unexpected: order-of-magnitude improvements normally lead to many surprises!
While the EVLA alone will make many new discoveries, instrumentation at other wavelengths has improved enormously as well. Hence this conference will empahsize synoptic approaches addressing, for example, comparison of high energy and non-thermal radio emission, or parallel imaging of radio and infrared molecular emission/absorption and continuum emission.
