Title: A KINEMATIC DISTANCE STUDY OF THE PLANETARY NEBULAE-SUPERNOVA REMNANT-H II REGION COMPLEX AT G35.6–0.5

Abstract

Two possible planetary nebulae (PN G035.5–00.4 and IRAS 18551+0159), one newly re-identified supernova remnant (SNR G35.6–0.4), and one H II region (G35.6–0.5) form a line-of-sight-overlapping complex known as G35.6–0.5. We analyze 21 cm H I absorption spectra toward the complex to constrain the kinematic distances of these objects. PN G035.5–00.4 has a distance from 3.8 ± 0.4 kpc to 5.4 ± 0.7 kpc. IRAS 18551+0159 is at 4.3 ± 0.5 kpc. We discuss the distance for SNR 35.6–0.4, for which the previous estimate was 10.5 kpc, and find a plausible distance of 3.6 ± 0.4 kpc. The new distance of SNR G35.6–0.4 and the derived mass for the ∼55 km s{sup –1} CO molecular cloud can accommodate an association with HESS J1858+020. We also conclude that SNR G35.6–0.4 is unlikely to be associated with PSR J1857+0210 or PSR J1857+0212, which are projected onto the SNR area.
