Optically Thick Winds from Degenerate Dwarfs. I. Classical Nova of Populations I and II
Twenty six sequences of optically thick wind solutions have calculated which mimic time-dependent evolution of classical novae of populations I and II. The peak of the new opacity around log T = 5:2 due to iron lines is found to be strong enough to accelerate the winds even in very low iron abundance such as Z=0.001 for massive white dwarfs ( 0:8M ). The old population novae show the slow light...
متن کاملSuzaku Detection of Super-hard X-ray Emission from the Classical Nova V2491 Cygni
We report the detection of super-hard (>10 keV) X-ray emission extending up to 70 keV from the classical nova V2491 Cygni using the Suzaku observatory. We conducted two ∼20 ks target-ofopportunity observations 9 and 29 days after the outburst on 2008 April 11, yielding wide energy range spectra by combining the X-ray Imaging Spectrometer and the Hard X-ray Detector. On day 9, a spectrum was obt...
متن کاملSubmillimeter Continuum Emission from Comets
We report submillimeter continuum observations of five comets obtained at the James Clerk Maxwell Telescope on Mauna Kea. Two of the five comets (P/Brorsen-Metcalf and Okazaki-Levy-Rudenko) were detected at 800-~m wavelength, while physically significant upper limits were placed on the other three (Austin 1989Cl, P/Faye, and Levy 1990c). We compare the JCMT • data with millimeter continuum meas...
متن کاملCONTINUUM EMISSION FROM GALAXIES AT z ≃ 3
We report the detection of significant Lyman continuum flux in the composite spectrum of 29 Lyman break galaxies (LBGs) with redshifts 〈z〉 = 3.40 ± 0.09. After correction for opacity due to intervening absorption using a new composite QSO spectrum evaluated at the same redshift, the ratio of emergent flux density at 1500 Å in the rest frame to that in the Lyman continuum is L(1500)/L(900) = 4.6...
متن کاملContinuum Acceleration of Black Hole Winds
Motivated by recent observations of high-velocity, highly ionized winds in several QSOs, models of purely continuum-driven winds launched from ∼ 200 GMBH/c2 are presented. Launching conditions are investigated, as well as the observational signatures for a variety of initial conditions and illuminating continua. While we verify that continuum-driven, highly-ionized outflows reach the observed v...
