HD 100546 shows hints of additional extended emission presumably a residual protostellar envelope also visible in scattered light at optical wavelengths. For TW Hya HCO+ J=1-0 line emission from the circumstellar disk is detected and spatially resolved. The observed size and intensity are in good...

Evidence for a planetary companion to HD 100546 was gathered using the UVES echelle spectrograph at the VLT in Chile. This confirms other data indicating a planetary companion. The planet's size puts it near the border between a giant planet and a brown dwarf. Spectroscopic analysis of mid-IR...
