    Asteroseismic analysis of the pre-main-sequence stars in NGC 2264 
    Guenther, David B.; Kallinger, T.; Zwintz, K.; Weiss, W. W.; Kuschnig, R.; Casey, M. P.; Matthews, J. M.; Moffat, A. F. J.; Rucinski, S. M.; Sasselov, D.; Walker, G. A. H. (American Astronomical Society, 2009-10-20)
    NGC 2264 is a young open cluster lying above the Galactic plane in which six variable stars have previously been identified as possible pre-main-sequence (PMS) pulsators. Their oscillation spectra are relatively sparse ...

    Destruction of massive fragments in protostellar disks and crystalline silicate production 
    Vorobyov, Eduard I. (IOP Publishing, 2011-02-20)
    We present a mechanism for the crystalline silicate production associated with the formation and subsequent destruction of massive fragments in young protostellar disks. The fragments form in the embedded phase of star ...

    Into the void : simulations of protostellar jets from Keplerian discs extended to observational length scales 
    Ramsey, Jonathan Paul (Halifax, N.S. : Saint Mary's University, 2011)
    In this work, I present the first simulations to investigate the formation and propagation of protostellar jets that simultaneously include the launching mechanism at < 0.1 AU and the much larger observational length scales ...

    Star formation near Berkeley 59: embedded protostars 
    Majaess, Daniel J.; Rosvick, J. M. (American Astronomical Society, 2013-12)
    A group of suspected protostars in a dark cloud northwest of the young (∼2 Myr) cluster Berkeley 59 and two sources in a pillar south of the cluster have been studied in order to determine their evolutionary stages and ...
