On the Visibility of Solar Prominences in SDO/AIA Channels
Original language description
Prominences in EUV lines are observed as dark structures over the limb due absorption and emission blocking mechanisms. However, at 171 ? is observed emission in prominences with TRACE and SDO/AIA, and it is believed to be due to the prominence-corona transition region (PCTR) emitting in cool lines. To check this, we use the Differential Emission Measure (DEM) recently obtained for quiescent prominences using SOHO/SUMER spectra (Parenti and Vial 2007) and compute the synthetic spectra in selected AIA channels. We then compare 171 ? and 195 ? channels and derive conclusions concerning the PCTR emissivity, as well well as the absorption and blocking. The emission seen in the 171 ? channel can be used to better constrain prominence DEM curves.
