Proper Motions of the Ansae in the Planetary Nebula NGC 7009
Luis F. Rodriguez, Yolanda Gomez
For the planetary nebula NGC 7009, we present a comparison of two unpublished Very Large Array archive data sets taken with a time separation of 8.09 years to confirm the proper mo…
Detection of HCO+ Emission toward the Planetary Nebula K 3-35
D. Tafoya, Y. Gomez, G. Anglada +8
We report the detection, for the first time, of HCO+ (J=1-0) emission as well as marginal CO (J=1-0) emission toward the planetary nebula (PN) K3-35 as a result of a molecular surv…
VLA H53alpha and H92alpha line observations of the central region of NGC 253
C. A. Rodriguez-Rico, W. M. Goss, J. -H. Zhao +2
We present new Very Large Array (VLA) observations toward NGC 253 of the recombination line H53alpha (43 GHz) at an angular resolution of 1.''5 X 1.''0. The free-free emission at 4…
Expansion Parallax for the Compact Planetary Nebula M2-43
L. Guzman, Y. Gomez, L. F. Rodriguez
We present high quality radio continuum observations made with the Very Large Array (VLA) at 3.6 cm at two epochs toward the planetary nebula M2-43. The comparison of the two epoch…
