Abstract (from CDS):

We present results from optical spectra for intermediate-mass stars in the young cluster Trumpler 37. The spectroscopy presented helps to refine the membership, reddening (AV∼1.5±0.5), and distance modulus [(m-M)=9.7±0.2] to this cluster. Only three new emission-line stars were found in our sample, resulting in a total of four stars in the cluster with emission lines and spectral type earlier than G. One of these emission-line stars, LkHα 349, is probably not a member of the central cluster, since it lies within a dark globule on the periphery of the H II region IC 1396. Thus, at an age of about 3 Myr, as estimated from the expansion age of molecular material around the cluster, emission-line phenomena possibly driven by disk accretion are extremely rare through spectral types F (masses ≳1.5 M).
