Imaging the Haro 6-10 Infrared Companion.
We present an infrared imaging study of the low-mass pre-main-sequence binary system Haro 6-10. This system is one of a handful in which the optically visible primary has the characteristics of a normal T Tauri star, while the secondary is a so-called "infrared companion" (IRC), a strongly extincted object that emits most of its luminosity in the infrared. A speckle holographic technique was us...
متن کاملThe near - infrared and ice - band variability of Haro 6 - 10
We have monitored the angularly resolved near infrared and 3.1 μm ice-band flux of the components of the young binary Haro 6-10 on 23 occasions during the years 1988 to 2000. Our observations reveal that both the visible star Haro 6-10 (Haro 6-10S) and its infrared companion (Haro 6-10N) show significant variation in flux on time scales as short as a month. The substantial flux decrease of Haro...
متن کامل6 A photoionized Herbig - Haro object in the Orion nebula
The spectra of Herbig Haro objects are usually characteristic of ionization and excitation in shock-heated gas, whether an internal shock in an unsteady outflow or a bow shock interface with the interstellar medium. We examine the eastern-most shock – the leading optically visible shock – of a Herbig Haro outflow (HH 529) seen projected on the face of the Orion Nebula, using deep optical echell...
متن کاملMid Infrared Observations of Van Maanen 2: No Substellar Companion
The results of a comprehensive infrared imaging search for the putative 0.06M⊙ astrometric companion to the 4.4 pc white dwarf van Mannen 2 are reported. Adaptive optics images acquired at 3.8μm reveal a diffraction limited core of 0.09 and no direct evidence of a secondary. Models predict that at 5 Gyr, a 50MJ brown dwarf would be only 1 magnitude fainter than van Maanen 2 at this wavelength a...
متن کاملMixing in Haro Strait
The first task after the cruise was to organize and calibrate the large quantities of acoustic and hydrographic data collected by the IOS group. Most of the dataset was then archived onto CD-ROMs to allow for easy distribution among co-investigators. A cruise report containing information about deployments and instrument logs, as well as summarizing preliminary results was written by Rich Pawlo...
