The Circumstellar Environment of High-Mass Protostellar Objects: IV. C17O Observations and Depletion

H. S. Thomas, G. A. Fuller

We observe 84 candidate young high-mass sources in the rare isotopologues C17O and C18O to investigate whether there is evidence for depletion (freeze-out) towards these objects. O…

A 1.3 cm wavelength radio flare from a deeply embedded source in the Orion BN/KL region

Jan Forbrich, Karl M. Menten, Mark J. Reid

Aims: Our aim was to measure and characterize the short-wavelength radio emission from young stellar objects (YSOs) in the Orion Nebula Cluster and the BN/KL star-forming region. M…

Simultaneous Doppler maps of IP Peg in outburst

C. Papadaki, H. M. J. Boffin, D. Steeghs

IP Pegasi is an eclipsing dwarf nova lying above the period gap with an orbital period of 3.8h. It is the first cataclysmic variable to show evidence of spiral arms in its accretio…

The ROSAT North Ecliptic Pole Survey: The Optical Identifications

I. M. Gioia, J. P. Henry, C. R. Mullis +4

The X-ray data around the North Ecliptic Pole (NEP) of the ROSAT All Sky Survey have been used to construct a contiguous area survey consisting of a sample of 445 individual X-ray…

Intergalactic H_2 Photodissociation and the Soft UV Background Produced by Population III Objects

Benedetta Ciardi, Andrea Ferrara, Tom Abel

We study the effects of the ionizing and dissociating photons produced by PopIII objects on the surrounding intergalactic medium. We find that the typical size of a H_2 photodissoc…
