The Canis Major Star Forming Region
Jane Gregorio-Hetem
The shape of the main arc formed by the Canis Major clouds has been suggested to result from a supernova explosion possibly triggering the recent star formation activity. The prese…
Polarization of Herbig Ae/Be candidates and their environment
Claudia V. Rodrigues, Marilia J. Sartori, Jane Gregorio-Hetem +2
We present the V band polarization of 81 Herbig Ae/Be (HAeBe) candidates from the Pico dos Dias Survey (PDS). A good estimate of the foreground polarization was possible for most s…
Optical polarization and near IR photometry of the proto-planetary nebula Hen 3-1475
Claudia V. Rodrigues, Francisco J. Jablonski, Jane Gregorio-Hetem +2
We present BVRI CCD aperture polarization and near-infrared photometry of the proto-planetary nebula Hen 3-1475. Its intrinsic polarization is high and shows a strong spectral depe…
Discovery of a Luminous Quasar in the Nearby Universe
Carlos A. O. Torres, Germano R. Quast, Roger Coziol +4
In the course of the Pico dos Dias survey (PDS), we identified the stellar like object PDS456 at coordinates alpha = 17h 28m 19.796s, delta = -14deg 15' 55.87'' (epoch 2000), with…
