... 2009 August 3 . T Tauri: A Star is Formed . ... Explanation: What does a star look like when it is forming? The prototypical example is the variable star T Tauri , visible as the bright orange star near the image center. The orange star centered in this remarkable telescopic skyview is T Tauri, prototype of the class of T Tauri variable stars. ... To further complicate the picture, infrared observations indicate that T Tauri itself is part of a multiple star system. ... About APOD | ...

7. Warm Dust and Spatially Variable Polycyclic Aromatic Hydrocarbon Emission in
We present Spitzer observations of the nearby dwarf starburst galaxy NGC 1705 obtained as part of the Spitzer Infrared Nearby Galaxies Survey. ... The nebular metallicity of NGC 1705 falls at the transition level of ~0.35 Zsolar found by Engelbracht and collaborators, below which PAH emission is difficult to detect; the fact that a system at this metallicity shows spatially variable PAH emission demonstrates the complexity of interpreting diffuse 8 О?m emission in galaxies. ...
