Extremely red stellar objects revealed by IPHAS
N. J. Wright, R. Greimel, M. J. Barlow +13
We present photometric analysis and follow-up spectroscopy for a population of extremely red stellar objects extracted from the point-source catalogue of the INT Photometric H-Alph…
An occultation event in a triple post-AGB star
M. Hajduk, A. A. Zijlstra, K. Gesicki
We study the post-AGB central star of the (bipolar) Galactic bulge planetary nebula M 2-29. We have obtained additional HST imaging and SAAO spectroscopy of the object. The star sh…
Morphologies of the Nebulae around "born-again" Central Stars of Planetary Nebulae
S. Kimeswenger, A. A. Zijlstra, P. A. M. van Hoof +5
While in the past spherodicity was assumed, and still is used in modeling of most nebulae, we know now that only a small number of planetary nebulae (PNe) are really spherical or a…
Symmetry and Asymmetry in "born again" Planetary Nebulae
S. Kimeswenger, A. A. Zijlstra, P. A. M. van Hoof +4
While in the past spheroidicity was assumed, and still is used in modeling of most nebulae, we know now that only a small number of planetary nebulae (PNe) are really spherical or…
The enigma of the oldest `nova': the central star and nebula of CK Vul
M. Hajduk, Albert A. Zijlstra, P. A. M. van Hoof +9
CK Vul is classified as, amongst others, the slowest known nova, a hibernating nova, or a very late thermal pulse object. Following its eruption in AD 1670, the star remained visib…
Near-infrared VLT adaptive optics imaging of evolved stars
Eric Lagadec, Olivier Chesneau, Albert A. Zijlstra +2
The high angular resolution and dynamic range achieved by the NACO adaptive optics system on the VLT is an excellent tool to study the morphology of Planetary Nebulae (PNe). We obs…
