نویسنده
چکیده
We present a high–resolution study of NGC 2264 IRS1 in CS 2→1 and in the 3-mm continuum using the IRAM Plateau de Bure Interferometer. We complement these radio data with images taken at 2.2 µm, 4.6 µm, and 11.9 µm. The combined information allow a new interpretation of the closest environment of NGC 2264 IRS1. No disk around the B–type star IRS1 was found. IRS1 and its low–mass companions are located in a low–density cavity which is surrounded by the remaining dense cloud core which has a clumpy shell–like structure. Strong evidence for induced on– going star formation was found in the surroundings of IRS1. A deeply embedded very young stellar object 20 ′′ to the north of IRS1 is powering a highly collimated bipolar outflow. The object 8 in the closer environment of IRS1 is a binary surrounded by dusty circumbinary material and powering two bipolar outflows.

A previously unpublished ultralow–dispersion spectrum of Sanduleak -69 202, the stellar progenitor of SN 1987A, is presented and the uncertain presupernova evolution of Sanduleak -69 202 is discussed.

We are carrying out a search for Lyα emitting galaxies at z = 6.5 employing slitless spectroscopy at the VLT. In our 43 arcmin field we find three isolated single emission lines with SEDs consistent with line emitting galaxies at z = 6.5.
