H $_{2}$ in low-ionization structures of planetary nebulae

Stavros Akras, Denise R. Gonçalves, Gerardo Ramos-Larios

We report the detection of near-IR H $_{2}$ emission from the low-ionization structures (knots) in two planetary nebulae. The deepest ever, high-angular resolution H $_{2}$ 1-0 S(1) at 2…

Proof of shock-excited H $_{2}$ in low-ionization structures of PNe

Stavros Akras, Denise R. Gonçalves, Gerardo Ramos-Larios

We report the detection of near-IR H $_{2}$ lines emission from low-ionization structures (LISs) in planetary nebulae. The deepest, high-angular resolution H $_{2}$ 1-0 S(1) at 2.122 $μ$ …
