Popis: | A 56 ks soft X‐ray image of the IC 2391 star cluster has been acquired with the ROSAT High Resolution Imager, resulting in the detection of 34 sources above a 3 σ detection level of \documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage[OT2,OT1]{fontenc} \newcommand\cyr{ \renewcommand\rmdefault{wncyr} \renewcommand\sfdefault{wncyss} \renewcommand\encodingdefault{OT2} \normalfont \selectfont} \DeclareTextFontCommand{\textcyr}{\cyr} \pagestyle{empty} \DeclareMathSizes{10}{9}{7}{6} \begin{document} \landscape $L_{\mathrm{X}\,}\simeq 4\times 10^{28}$ \end{document} ergs s−1. We report source coordinates and fluxes plus identifications and broadband BVRI photometry for optical counterparts to each source. We compare these results with X‐ray source fluxes from a ROSAT PSPC image of the same region, whic... |
