Limits on molecular emission from the planetary nebula associated with Sakurai's object.

EVANS A., EYRES S.P.S., NAYLOR T. and SALAMA A.

Abstract (from CDS):

We have observed Sakurai's object in the S(1)λ2.121 line of H2 and in the J=2->1 line of 12CO. We give upper limits on the H2 and 12CO emission from the planetary nebula associated with this object. Assuming a distance of 3.8 kpc, we obtain an upper limit on the mass of molecular hydrogen in the planetary nebula of 1.8x10–4M☉ for an excitation temperature of 1000 K and, for an excitation temperature of 25K, an upper limit of 1.5x10–5M☉ on the mass of CO.
