A Dust-Scattering Model for M1-92: A Revised Estimate of the Mass Distribution and Inclination
Preplanetary nebulae (PPNe) are formed from mass-ejecting late-stage AGB stars. Much of the light from the star gets scattered or absorbed by dust particles, giving rise to the observed reflection nebula seen at visible and near-IR wavelengths ...

Optical Spectroscopy and Photoionization Model of Planetary Nebula NGC 6572
We investigated NGC 6572 through optical spectroscopy to determine its kinematical and chemical properties. Two intermediate dispersion spectra (R~5000) centered around Hα and Hβ were used to derive the nebular expansion velocity from emission lines ...
