The Hydrogen Burning Turn-off of Rs Ophiuchi 2006
We report a coordinated multi-band photometry of the RS Oph 2006 outburst and highlight the emission line free y-band photometry that shows a mid-plateau phase at y ∼ 10.2 mag from day 40 to day 75 after the discovery followed by a sharp drop of the final decline. Such mid-plateau phases are observed in other two recurrent novae, U Sco and CI Aql, and are interpreted as a bright disk irradiated...
متن کاملGround-based Optical and Spitzer Infrared Imaging Observations of Comet 21p/giacobini-zinner
We present ground-based optical and Spitzer Space Telescope infrared (IR) imaging observations of the ecliptic (Jupiter-family) comet 21P/Giacobini-Zinner, the parent body of the Draconid meteor stream, during its 2005 apparition. The onset of nucleus activity occurred at a pre-perihelion heliocentric distance, rh 3.80 AU, while post-perihelion 21P was dusty (peak Afρ = 131 cm−1) and active out...
متن کاملSwift Observations of Shock Evolution in RS Ophiuchi
Our Swift observations of RS Oph form an unprecedented X-ray dataset to undertake investigations of both the central source and the interaction of the outburst ejecta with the circumstellar environment. Over the first month, the XRT data are dominated by emission from rapidly evolving shocks. We discuss the differences in derived parameters from those found for RXTE at early times and the evolu...
متن کاملInterferometric Observations of RS Ophiuchi and the Origin of the Near-IR Emission
We report observations of the recurrent nova RS Oph using long-baseline near-IR interferometry. We are able to resolve emission from the nova for several weeks after the February 2006 outburst. The near-IR source initially expands to a size of ∼ 5 milli-arcseconds. However, beginning around day 10 the IR source appears to begin to shrink, reaching ∼ 2 milli-arcseconds by day 100. We combine our...
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
