An Adaptive Optics Survey of M8-M9 stars: Discovery of 4 Very Low Mass Binaries With at Least One System Containing a Brown Dwarf Companion
Use of the highly sensitive Hokupa’a/Gemini curvature wavefront sensor has allowed for the first time direct adaptive optics (AO) guiding on M8-M9 very low mass (VLM) stars. An initial survey of 20 such objects (SpT=M8-M9) discovered 4 binaries. Three of the systems have separations of less than 4.2 AU and similar mass ratios (∆K < 0.8 mag; 0.85 < q < 1.0). One system, however, did have the lar...
متن کاملDiscovery of a Tight Brown Dwarf Companion to the Low Mass Star LHS 2397a
Using the adaptive optics system, Hokupa’a, at Gemini-North, we have directly imaged a companion around the UKIRT faint standard M8 star, LHS 2397a (FS 129) at a separation of 2.96 AU. Near-Infrared photometry of the companion has shown it to be an L7.5 brown dwarf and confirmed the spectral type of the primary to be M8. We also derive a substellar mass of the companion of 0.068M⊙, although mas...
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...
متن کاملDiscovery of a Very Nearby Brown Dwarf to the Sun: a Methane Rich Brown Dwarf Companion to the Low Mass Star Scr
We present VLT/NACO SDI images of the very nearby star SCR 1845-6357 (hereafter SCR 1845). SCR 1845 is a recently discovered (Hambly et al. 2004) M8.5 star just 3.85 pc from the Sun (Henry et al. 2006). Using the capabilities of the unique SDI device, we discovered a substellar companion to SCR 1845 at a separation of 4.5 AU (1.170”±0.003” on the sky) and fainter by 3.57±0.057 mag in the 1.575 ...
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...
