Hubble space telescope expansion parallaxes of the planetary nebulae
We have combined two epochs of Hubble Space Telescope WFPC2 imaging data with ground-based expansion velocities to determine distances to three planetary nebulae (NGC 6578, NGC 6884, and IC 2448). We used two variants of the expansion parallax technique—a gradient method and a magnification method— to determine the distances. The results from the two methods agree to within the errors. A fourth...
متن کاملHubble Space Telescope Fine Guidance Sensor Parallaxes of Galactic Cepheid Variable Stars: Period-luminosity Relations
We present new absolute trigonometric parallaxes and relative proper motions for nine Galactic Cepheid variable stars: l Car, ζ Gem, β Dor, W Sgr, X Sgr, Y Sgr, FF Aql, T Vul, and RT Aur. We obtain these results with astrometric data from Fine Guidance Sensor 1r, a white-light interferometer on Hubble Space Telescope. We find absolute parallaxes in milliseconds of arc: l Car, 2.01± 0.20 ; ζ Gem...
متن کاملCOSMOS : Hubble Space Telescope Observations
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Here we review the characteristics of the HST imaging with the Advanced Camera for Surveys (ACS) and parallel observations with NICMOS and WFPC2. A square field (1.8⊓⊔) has been imaged with single-orbit ACS I-F814W expos...
متن کاملIntelligent Scheduling of Hubble Space Telescope Observations
This paper describes the S PIKE system, a general framework for scheduling which has been developed by the Space Telescope Science Institute for NASA’s Hubble Space Telescope (HST). Efficient use of astronomical observatories is very important to the scientific community: the demand for research-grade telescopes far exceeds the supply. The need for efficient scheduling is especially keen for sp...
متن کاملHubble Space Telescope Imaging of 11 Carinae
We present new high spatial resolution observations of the material around 11 Carinae obtained with the Hubble Space Telescope Wide Field/Planetary Camera. The star 11 Carinae is one of the most massive and luminous stars in our Galaxy, and has been episodically expelling significant quantities of gas over the last few centuries. The morphology of the bright central nebulosity (the homunculus) ...
