Pushing the limits: detecting H2 emission from faint bipolar planetary nebulae in the IPHAS sample
Gerardo Ramos-Larios, Martin A. Guerrero, Laurence Sabin +1
We have obtained deep narrowband images in the near-infrared H2 (2.122 microns) emission line for a sample of 15 faint Isaac Newton Telescope Photometric Halpha Survey (IPHAS) bipo…
The remarkable outburst of the highly evolved post-period-minimum dwarf nova SSS J122221.7-311525
V. V. Neustroev, T. R. Marsh, S. V. Zharikov +22
We report extensive 3-yr multiwavelength observations of the WZ Sge-type dwarf nova SSS J122221.7-311525 during its unusual double superoutburst, the following decline and in quies…
Catching a Grown-Up Starfish Planetary Nebula: I. Morpho-Kinematical study of PC 22
L. Sabin, M. A. Gómez-Muñoz, M. A. Guerrero +9
We present the first part of an investigation on the planetary nebula (PN) PC 22 which focuses on the use of deep imaging and high resolution echelle spectroscopy to perform a deta…
