Transition disk based on the excess at 24 micron. (III) – Class III based on SED with incomplete IRAC data, but detected flux at 24 micron. Models: K = Kurucz, NG=NextGen (Baraffe et al. 1998), C = COND2000 (Chabrier et al. 2000), Si = Siess (Siess et al. 2000). Effective temperatures and masses were derived using VOSA (Bayo et al. 2008, assuming Log g = 4.0), and using 5 Myr isochrones (Siess et al. 2000; and Chabrier et al. 2000). Ages are estimated from a HR diagram, using VOSA (Bayo et al. 2008, assuming Log g = 4.0) and several isochrones. Spectral types and equivalent withs from: S = Sacco et al. (2008), D = D&M (1999), B = Bayo (2009) (Ph.D. Thesis).

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.
