WFPC2 Stellar Photometry with HSTphot
HSTphot, a photometry package designed to handle the undersampled PSFs found in WFPC2 images, is introduced and described, as well as some of the considerations that have to be made in order to obtain accurate PSF-fitting stellar photometry with WFPC2 data. Tests of HSTphot’s internal reliability are made using multiple observations of the same field, and tests of external reliability are made ...
متن کاملImaging and photometry of comet C/1999 S4 (LINEAR) before perihelion and after breakup.
We analyzed photometric measurements and images of comet C/LINEAR before perihelion and after its breakup. Results from our photometry data include a lower limit of 0.44 kilometer for the radius of the nucleus before breakup, and a determination that it was depleted in carbon-chain molecules relative to most other comets. Our imaging and modeling results, which include a constraint on the rotat...
متن کاملStellar Photometry with CCD Sub - Pixel SensitivityVariationsA
The variation of sensitivity within a pixel of a CCD can be substantial and also substantially the same for each pixel of the CCD. Variations of the order of 10%, now being found for CCDs, can lead to errors in stellar photometry on the order of a few percent, dependent on the size of the stellar image and the position of its center within the pixel. An enhanced version of Starman, a proole tti...
متن کاملDetection with HARPS velocimetry and transit search with Spitzer photometry
We report on the detection of GJ 3634b, a super-Earth of mass m sin i = 7.0 −0.8 M⊕ and period P = 2.64561 ± 0.00066 day. Its host star is a M2.5 dwarf, has a mass of 0.45 ± 0.05 M , a radius of 0.43 ± 0.03 R and lies 19.8 ± 0.6 pc away from our Sun. The planet is detected after a radial-velocity campaign using the ESO/Harps spectrograph. GJ 3634b had an a priori geometric probability to underg...
متن کاملTransit and secondary eclipse photometry in the near - infrared
Near-infrared photometry of transiting extrasolar planets can be of great scientific value. It is however not straightforward to reach the necessary millimagnitude precision. Here we report on our attempts to observe transits and secondary eclipses of several extrasolar planets at 2.2 μm. Best results have been obtained on OGLE-TR-113b using the SOFI near-infrared camera on ESO’s New Technology...
