OBSERVATIONS OF THE LIMB SOLAR-FLARE ON 1980 APRIL 30 WITH THE SMM X-RAY POLYCHROMATOR

Autor: Gabriel, A, Acton, L, Culhane, J, Phillips, K, Wolfson, C, Rapley, C, Antonucci, E, Bentley, R, Jordan, C, Kayat, M, Leibacher, J, Levay, M, Sherman, J, Strong, K, Veck, N

Soft X-ray observations of the limb event on 1980 April 30 are summarized. These consist of maps made with the Flat Crystal Spectrometer and calcium and iron spectra obtained with the Bent Crystal Spectrometer. The physical conditions, e.g., temperat

X-RAY-SPECTRA OF SOLAR-FLARES OBTAINED WITH A HIGH-RESOLUTION BENT CRYSTAL SPECTROMETER

Autor: Culhane, J, Gabriel, A, Acton, L, Rapley, C, Phillips, K, Wolfson, C, Antonucci, E, Bentley, R, Catura, R, Jordan, C, Kayat, M, Kent, B, Leibacher, J, Parmar, A, Sherman, J, Springer, L, Strong, K, Veck, N

Preliminary results obtained for three solar flares with the bent crystal spectrometer on the SMM are presented. Resonance and satellite lines of Ca XIX and XVIII and Fe XXV and XXIV are observed together with the Fe XXVI Lyman-alpha line. Plasma pro

Publikováno v: ASTROPHYSICAL JOURNAL. 244(3)

Preliminary results of spectroscopy and imaging of a solar active region and flare plasma in soft X-ray emission lines are presented. Observed X-ray line widths in a nonflaring active region are broader than the Doppler width corresponding to the loc

Imaging X-ray astronomy : the Cygnus Loop SNR

Autor: Kayat, Michael Anthony

Supernovae and supernova remnants (SNR) are probably important energy sources in the interstellar medium (ISM) and an understanding of the intermediate and advanced stages of SNR evolution are particularly essential. This thesis describes, first a br
