Emission Line Variability of the Accreting Young Brown Dwarf 2MASSW J1207334-393254: From Hours to Years
We have obtained a series of high-resolution optical spectra for 2MASSW J1207334-393254 (2M1207). Two consecutive observing nights at the ESO Very Large Telescope with the UVES spectrograph yielded a timeseries with a resolution of ∼ 12min. Additional high-resolution optical spectra were obtained months apart at the Magellan Clay telescope using the MIKE instrument. Combined with previously pub...
متن کاملHst Nicmos Imaging of the Planetary-mass Companion to the Young Brown Dwarf 2massw J1207334 393254
Multiband (0.9Y1.6 m) images of the TW Hydrae association (TWA) brown dwarf 2MASSW J1207334 393254 (also known as 2M 1207) and its candidate planetary-mass companion (2M 1207b) were obtained on 2004 August 28 and 2005 April 26 withHSTNICMOS. The images from these two epochs unequivocally confirm the two objects as a common proper motion pair (16.0 confidence). A new measurement of the proper mo...
متن کاملPhotometric variability of a young, low-mass brown dwarf
We report differential I-band and J-band photometry of S Ori 45, a cool (spectral type M8.5), young (1–8 Myr) brown dwarf of the σOrionis cluster with a likely mass estimated at around 20 times the mass of Jupiter. We detect variability (amplitudes ranging from 34 to 81 mmag) and observe a modulation at a period of 2.5–3.6 h in both optical and near-infrared light curves. The most recent optica...
متن کاملVariability in the Thermal Emission from Accreting Neutron Star Transients
The composition of the outer 100 m of a neutron star sets the heat flux that flows outwards from the core. For an accreting neutron star in an X-ray transient, the thermal quiescent flux depends sensitively on the amount of hydrogen and helium remaining on the surface after an accretion outburst and on the composition of the underlying ashes of previous H/He burning. Because H/He has a higher t...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
