We use a time-dependent hydrodynamic code and non-LTE Monte Carlo to model disk dissipation for the Be star 66 Ophiuchi. compiled 63 years of observations from 1957 2020 encompass complete history growth subsequent star's disk. Our models are constrained by new archival photometry, spectroscopy polarization observations, allowing us event. Using Markov chain methods, we find Oph is consistent w...

The past 60 years have seen large reductions in vehicle emissions of particulate matter (PM), nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbons (HCs), sulfur dioxide (SO2), and lead (Pb). Advanced emission after-treatment technologies been developed for gasoline diesel vehicles to meet increasingly stringent regulations, yielding absolute from the on-road fleet despite increased miles t...
