First large scale Herbig-Haro jet driven by a proto-brown dwarf
B. Riaz, C. Briceno, E. Whelan +1
We report the discovery of a new Herbig-Haro jet, HH 1165, in SOAR narrow-band imaging of the vicinity of the sigma Orionis cluster. HH 1165 shows a spectacular extended and collim…
3-D Photoionization Structure and Distances of Planetary Nebulae IV. NGC 40
Hektor Monteiro, Diego Falceta-Gonçalves
Continuing our series of papers on the 3-D structure and accurate distances of Planetary Nebulae (PNe), we present here the results obtained for the planetary nebula NGC\,40. Using…
Orion's Bar: Physical Conditions across the Definitive H+ / H0 / H2 Interface
E. W. Pellegrini, J. A. Baldwin, G. J. Ferland +2
Previous work has shown the Orion Bar to be an interface between ionized and molecular gas, viewed roughly edge on, which is excited by the light from the Trapezium cluster. Much o…
Donut: measuring optical aberrations from a single extra-focal image
A. Tokovinin, S. Heathcote
We propose a practical method to calculate Zernike aberrations from analysis of a single long-exposure defocused stellar image. It consists in fitting the aberration coefficients a…
Proper Motions of the HH 47 Jet Observed with the Hubble Space Telescope
P. Hartigan, S. Heathcote, J. Morse +2
We present a proper motion study of the shock waves within the classic stellar jet HH 47 based on Hubble Space Telescope H-alpha and [S II] images of the region taken over two epoc…
The Three-Dimensional Circumstellar Environment of SN 1987A
Ben E. K. Sugerman, Arlin P. S. Crotts, William E. Kunkel +2
We present the detailed construction and analysis of the most complete map to date of the circumstellar environment around SN 1987A, using ground and space-based imaging from the p…
