An imaging study of the bipolar nebula Frosty Leo is presented. In particular, we have studied the effects of spatial distribution of H2O ice on the circumstellar environment. Using the Keck telescope with the NIRC infrared camera, we have recovered images at a wavelength of 3.08 μm within the prominent (attenuation of about 5 mag) water-ice absorption band, and in the adjacent quasi-continuum ...

We have discovered multiple jet-like features in the inner regions of the protoplanetary nebula (PPN) Frosty Leo, in optical images obtained with the Hubble Space Telescope. Frosty Leo is only the second PPN (after CRL2688) and the first oxygen-rich one, to show well-focussed jets close to the equatorial plane. The nebula consists of two bright compact structures embedded inside two large tenuo...

As I sat by my father's bed the man in the next bed asked for a cup of tea. There was some gentle banter about not being the proper time for tea, and the man ended the exchange by saying that it was, af...
