Number ratios of young stellar objects in embedded clusters
S. Schmeja, R. S. Klessen, D. Froebrich
Embedded clusters usually contain young stellar objects in different evolutionary stages. We investigate number ratios of objects in these classes in the star-forming regions rho O…
Symbiotic Miras vs. Planetary Nebulae in the Near Infrared
S. Schmeja, S. Kimeswenger
While symbiotic Miras and planetary nebulae are hard to distinguish by optical spectroscopy, their near infrared colors differ. We propose the near infrared two-color diagram to be…
DENIS Survey Data Probing Different Types of PNe
S. Schmeja, S. Kimeswenger
We present near-infrared photometry of a large sample of planetary nebulae (PNe) and show that the IJK colours are a good tool to distinguish different classes of PNe, like nebulae…
A catalogue of IJK photometry of Planetary Nebulae with DENIS
S. Schmeja, S. Kimeswenger
Near-infrared photometry of planetary nebulae (PNe) allows the classification of those objects. We present the largest homogeneous sample so far, obtained with the Deep Near Infrar…
New identification of the near infrared Source in the "born-again" planetary nebula A58 (=V605 Aql)
S. Kimeswenger, J. Koller, S. Schmeja
The central dust knot V605 Aql (= Nova Aql 1919) in the planetary nebula A58 is the result of a late-helium flash. Previous near infrared (NIR) measurements yield very bright fluxe…
