Abstract

We present 850Âµm and 450Âµm data from the JCMT Gould Belt Survey obtained with SCUBA-2 and characterise the dust attributes of Class I,Class II and Class III disk sources in L 1495. We detect 23% of the sample at both wavelengths, with the detection rate decreasing through the Classes from I–III.The median disk mask is 1.6Ã10−3 M,and only 7% of Class II sources have disk masses larger than 20 Jupiter masses. We detect a higher proportion of disks towards sources with stellar hosts of spectral type K than spectral type M. Class II disks with single stellar hosts of spectral type K have higher masses than those of spectral type M, supporting the hypothesis that higher mass stars have more massive disks. Variations in disk masses calculated at the two wavelengths suggests there may be differences in dust opacity and/or dust temperature between disks with hosts of spectral types K to those with spectral type M.
