High-resolution polarimetry of Parsamian 21: revealing the structure of an edge-on FU Ori disc
We present the first high spatial resolution near-infrared direct and polarimetric observations of Parsamian 21, obtained with the VLT/NACO instrument. We complemented these measurements with archival infrared observations, such as HST/WFPC2 imaging, HST/NICMOS polarimetry, Spitzer IRAC and MIPS photometry, Spitzer IRS spectroscopy as well as ISO photometry. Our main conclusions are the followi...
متن کاملPromises and Pitfalls of Polarimetry
Imagine an observational technique, differential in nature, that takes full advantage of the information content a photon has to offer. Photometric conditions would be unecessary, allowing groundbased telescopes to outsrip their space-based counterparts for uses where imaging is not required. Indeed, such a technique has been around for decades in the form of polarimetry. Why, then, are the num...
متن کاملOn the Nature of the Binary Components of Rxj0806.3+1527
We present imaging circular polarimetry and near-infrared photometry of the suspected ultra-short period white-dwarf binary RXJ0806.3+1527 obtained with the ESO VLT and discuss the implications for a possible magnetic nature of the white dwarf accretor and the constraints derived for the nature of the donor star. Our V -filter data show marginally significant circular polarization with a modula...
متن کاملEvaluation of the total analytical error in the flame photometry method
Background and Objectives: For total analytical error, imprecision (SD) and bias, performance goals for laboratory tests have most often been developed. A total analytical error goal requires that the combination of errors from all sources (random and systematic errors) be within some acceptable limit. M...
متن کاملPolarimetry of comets 67P/Churyumov–Gerasimenko, 74P/Smirnova–Chernykh, and 152P/Helin–Lawrence
Aims. Polarimetric characteristics of comets at large heliocentric distances is a relatively unexplored area; we extend the idea by adding and analysing the data for three Jupiter family comets (JFCs). Methods. With the FORS2 instrument of the ESO VLT, we performed quasi-simultaneous photometry and polarimetry of three active JFCs 67P/Churyumov-Gerasimenko, 74P/Smirnova-Chernykh, and 152P/Helin...
