A Close View on the Protoplanetary Disk in the Bok Globule CB 26

Abstract

We present new sub-arcsecond-resolution near-infrared polarimetric imaging and millimetre interferometry data on the circumstellar disk system in the Bok globule CB26. The data imply the presence of a M ≥ 0.01 M⊙ edge-on-seen disk of > 400 AU in diameter, being in Keplerian rotation around a young ~0.35 M⊙ star. The mm dust emission from the inner 200 AU is highly optically thick, but the outer parts are optically thin and made of small dust grains. Planetesimal growth in the inner disk could neither be confirmed nor excluded. We argue that the CB 26 disk is a very young protoplanetary disk and show that it is comparable to the early solar system.
