We have used the InfraRed Array Camera (IRAC) onboard the Spitzer Space telescope to search for low mass companions of the nearby debris disk star epsilon Eridani. The star was obs…
Outflows from Massive YSOs as Seen with the Infrared Array Camera
Howard A. Smith, J. L. Hora, M. Marengo +1
The bipolar outflow from the massive star forming cluster in DR21 is one of the most powerful known, and in IRAC images the outflow stands out by virtue of its brightness at 4.5 um…
