Optical TiO and VO Band Emission in Two Embedded Protostars: IRAS 04369+2539 and IRAS 05451+0037

Hillenbrand, Lynne A.; Knapp, Gillian R.; Rebull, Luisa M. +2 more

Archival spectra from the Sloan Digital Sky Survey of two optically faint flat-spectrum protostars, IRAS 04369+2539 and IRAS 05451+0037, show strong emission-line features including—notably—clear and broad emission across several molecular bands of TiO and VO. The molecular emission is indicative of dense, warm circumstellar gas and has been seen …

A Spitzer-MIPS Search for Dust in Compact High-velocity H I Clouds

Elvis, Martin; Williams, Rik J.; Nicastro, Fabrizio +2 more

We employ three-band Spitzer-MIPS observations to search for cold dust emission in three neutral hydrogen compact high-velocity clouds (CHVCs) in the vicinity of the Milky Way. Far-infrared emission correlated with H I column density was previously reported in HVC Complex C, indicating that this object contains dust heated by the Galactic radiatio…
