PublicaciónThe low-excitation structures of planetary nebulae
The low excitation properties of the planetary nebula (PN) NGC 6720 are known to be unusual, and to imply large ring/core emission ratios. We point out that...

PublicaciónThe Lowest Mass White Dwarf
Extremely low mass white dwarfs are very rare objects likely formed in compact binary systems. We present MMT optical spectroscopy of 42 low-mass white dwarf...
