A new strongly X - ray flaring M 9 dwarf in the solar neighborhood ⋆
We report on the discovery of a very low mass (VLM) star in the solar neighborhood, originally identified as an optical counterpart of a flaring X−ray source detected in the ROSAT All-Sky survey. Optical spectroscopy and infrared photometry consistently reveal a spectral type of M 9 ± 0.5 and a distance of ≈ 11± 2 pc. The optical counterpart of 1RXS J115928.5−524717 shows a large proper motion ...
متن کاملthe black hole and the white dwarf
astrophysics is becoming now an integral part of general physics. considering the black hole theory ,which is a new and exciting branch of relativistic astrophysics, we see many connections between elementary particle physics and astrophysics. in this article we attempt to explain the development of star physics ,in an easy ,understandable manner. previous knowledge of relativistic theory or cl...
متن کاملSpitzer Observations of the Oldest White Dwarfs in the Solar Neighborhood
We present Spitzer 5–15 μm spectroscopy of one cool white dwarf and 3.6–8 μm photometry of 51 cool white dwarfs with Teff < 6000 K. The majority of our targets have accurate BVRIJHK photometry and trigonometric parallax measurements available, which enables us to perform a detailed model atmosphere analysis using their optical, nearand mid-infrared photometry with state-of-the-art model atmosph...
متن کاملSolar Radiation Absorbed on the Neighborhood Scale regarding the Rural Fabric in Cold Climate Regions
Environmental subjects, in general, and energy issues, in particular, do not have a prominent role in rural research projects in Iran, and this is accompanied by negative environmental consequences, such as excessive energy consumption in rural housing. A significant amount of energy in villages is used up by dwellings, and the form of rural fabric is a major factor affecting this issue. Most o...
متن کاملA Possible Brown Dwarf Companion to the White Dwarf Gd1400
An unresolved, likely L dwarf companion to the DA white dwarf GD1400 is reported. This would be only the second such system known, discovered 17 years after the prototype L dwarf, GD165B, was determined to be a companion to a white dwarf. Photometric observations and model predicted stellar parameters of the well studied white dwarf primary indicate that GD1400B has J−K & 2.0 and MK = 12.13 mag...
