Looking for dust and molecules in Nova V4743 Sagittarii.

NIELBOCK M. and SCHMIDTOBREICK L.

Abstract (from CDS):

We present 1.2 mm continuum images and spectral line observations of CO(1-0) and SiO(3-2) rotational transitions of the recent nova V4743 Sgr. The nova is detected at 1.2 mm showing a variable millimetre emission. Only upper limits of TA*=0.06K for CO and TA*=0.03K for SiO could be derived. We discuss the results in terms the nature of the millimetre emission favouring dust from a phase before the recent outburst as the likely radiating source. We also comment on the possibility of free-free emission from the ionised shell as the source of the measured millimetre radiation.
