Notes. The F12 column represents the 12 μm IRAS measurement (MSX C for LkHα 260). The column underneath “Neb” indicates whether an optical reflection nebula is present in the Digitized Sky Survey at 0.65 μm. In the last column we derived the 12 μm excess fraction of the circumstellar disks. For Hilt 641, AS 267, NGC 6530-45, and LkHa 112 we supply an upper limit of 0.1 Jy in the SiC filter.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
