We report the detection during the Chandra Orion Ultradeep Project (COUP) of two soft, constant, and faint X-ray sources associated with the Herbig-Haro object HH210. HH210 is located at the tip of...
Science with the James Webb space telescope (2006)
Gardner, Jonathan P., Mather, John C., Clampin, Mark, Doyon, Rene, Greenhouse, Matthew A., Hammel, Heidi B., ...
