Proper motions in the knotty, bipolar jet in Henize 2-90.

Abstract (from CDS):

Using second-epoch Hubble Space Telescope imaging of the unusual, bipolar jet source He 2-90, we have discovered proper motions of 0".03 yr–1 in the jet knots. Combining the proper motion with the knots' radial velocity measured from ground-based long-slit data, we find that the jet speed is roughly 150-360 km.s–1, the source distance is 1-2.5 kpc, and the inclination (to the sky plane) of the jet axis is θ=10°-4°, although smaller values of θ and larger values of the jet speed and distance are not ruled out. A comparison of the [O III] and [N II] images shows the central obscuring disk structure directly. The disk, seen nearly edge-on, is embedded within a low-excitation circumstellar region extending from the equator up to a latitudinal angle of about ±62°, with the remaining latitudinal angular space being occupied by a biconical high-excitation region whose symmetry axis is aligned along the jet. The jet is at least 1400 yr old; the knots are being ejected at the rate of one pair roughly every 35-45 yr (independent of the tilt angle and distance to He 2-90), and accretion is still occurring since the youngest jet material is only ∼10 yr old. The jet can be plausibly driven by an accretion disk around a low-mass companion in an eccentric orbit with a period of ∼40 yr, with increased accretion during periastron passage producing the jet knots.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
