The excitation mechanisms and evolutionary stages of UWISH2 planetary nebula candidates
Jones, Alex; Gledhill, Timothy; Froebrich, Dirk; Smith, Michael (2018-10-01)We present medium-resolution K-band long-slit spectroscopy of 29 true, likely, possible, and candidate Galactic Plane planetary nebulae (PNe) from the UWISH 2 survey, many of which have only been recently discovered. These ... -
Planetary Nebulae in the UWISH2 survey
Gledhill, Timothy; Froebrich, Dirk; Campbell-White, J.; Jones, Alex (2018-09-21)Near-infrared imaging in the 1 - 0 S(1) emission line of molecular hydrogen is able to detect planetary nebulae (PNe) that are hidden from optical emission line surveys.We present images of 307 objects from the UWISH2 ...
