| Abstract: | In the present paper we report on the difference in angular sizes between radio-loud and radio-quiet CMEs. For this purpose
we compiled these two samples of events using Wind/WAVES and SOHO/LASCO observations obtained during 1996 – 2005. We show that the radio-loud CMEs are almost twice as wide
as the radio-quiet CMEs (considering expanding parts of CMEs). Furthermore, we show that the radio-quiet CMEs have a narrow
expanding bright part with a large extended diffusive structure. These results were obtained by measuring the CME widths in
three different ways. |
