Title: A nascent Herbig Be star in a radiation-bathed globule of Cygnus X 

Abstract:
The Spitzer Space Telescope has revealed the rich morphology of the gas and 
dust of the Cygnus X molecular complex in its interaction with the hard 
radiation field of the nearby Cygnus OB2 association. Many of the structures 
seen in the interface between Cygnus X and the bubble blown by the injection of 
energy by Cygnus OB2 are globules and pillars, some of them displaying clear 
evidence of star formation in their densest parts. Here we focus on the globule 
IRAS 20319+3958, which is found to host a small embedded cluster of stars. The 
physical conditions of the embedding gas can be studied in detail through 
observations ranging from near infrared to the millimeter, including those 
provided by Herschel and SOFIA. Furthermore, the brightest stars of the cluster 
are only lightly obscured and spectra in the visible can be obtained. We 
present spectroscopic observations of the brightest cluster member, which turns 
out to be a Herbig Be star with photospheric HeI lines in absorption and 
intense Halpha and Hbeta emission with clear P Cygni profiles. FeII multiplet 
lines are clearly seen in emission as well. High-resolution infrared images 
show this star to be a binary with a projected separation of 800 AU. The 
companion has much redder colors, perhaps due to a denser circumstellar 
envelope.
