The use of Ks band photometric excesses to investigate H 2 emission in planetary nebulae
(2006)
We have determined the distribution of H2 emission in 14 planetary nebulae (PNe), using imaging and photometry published by the 2MASS infrared survey. This technique is only applicable under certain stringent conditions, ...

The dynamics of elongated and strongly stratified straits
(1998)
A three-dimensional frictional Ekman-type model has been derived from an analysis of the primitive momentum equations for the cases of long, strongly stratified straits. An analytical solution has been obtained. A set of ...

Polarimetry of R Aqr and PN M2-9
(2014)
The bipolar or more complex morphology observed in planetary nebulae have been explained by two principal hypothesis: by the existence of a companion and an accreting disk or by the effects of magnetic field, (or a combination ...
