Turbulence in Class 0 and Class I protostellar envelopes

D. Ward-Thompson, L. Hartmann, D. J. Nutter

We estimate the levels of turbulence in the envelopes of Class 0 and I protostars using a model based on measurements of the peak separation of double-peaked asymmetric line profil…

The Truncated Disk of CoKu Tau/4

Paola D'Alessio, Lee Hartmann, Nuria Calvet +11

We present a model of a dusty disk with an inner hole which accounts for the Spitzer Space Telescope Infrared Spectrograph observations of the low-mass pre-main sequence star CoKu…

Disk evolution in the Ori OB1 association

Nuria Calvet, Cesar Briceno, Jesus Hernandez +5

We analyze multi-band photometry of a subsample of low mass stars in the associations Ori OB1a and 1b discovered during the CIDA Orion Variability Survey, which have ages of 7 - 10…

Herbig Ae/Be Stars in nearby OB associations

Jesus Hernandez, Nuria Calvet, Lee Hartmann +4

We have carried out a study of the early type stars in nearby OB associations spanning an age range of 3 to 16 Myr, with the aim of determining the fraction of stars which b…

Collapse and Fragmentation in Finite Sheets

Andreas Burkert, Lee Hartmann

We present two-dimensional simulations of finite, self-gravitating gaseous sheets. Unlike the case of infinite sheets, such configurations do not constitute equilibrium states but…

Magnetospheres and Disk Accretion in Herbig Ae/Be Stars

J. Muzerolle, P. D'Alessio, N. Calvet +1

We present evidence of magnetically-mediated disk accretion in Herbig Ae/Be stars. Magnetospheric accretion models of Balmer and sodium profiles calculated with appropriate stellar…
