FGL 2 | DX Cha. Hen 3-741. Noted as possible binary (separation > 0".040) by | |
Baines et al. (2006) | Bns2006 | |
In eps Cha Association. 11596-7813 is also a member. | ||
11596-7813C = 12001-7812A. | ||
B, C, D, and E components were resolved by Feigelson et al. (2003) | Fgl2003 | |
using Chandra ACIS-I (Advanced CCD Imaging Spectrometer Imager). | ||
Additional wide components G, H, I, J, and K, as well as closer F | ||
companion were resolved by Grady et al (2004) using data from HST/STIS | Gry2004 | |
and VLT/NACO. Their theta values for AD and AE appear to be in error; | ||
correct values are perhaps 180-71=109deg and 180-74=106deg? | ||
Grady et al. provided no relative astrometry for the H, I, J, and K | ||
companions. Coarse values were extracted by the cataloguer using | ||
Aladin, based on their Figure 4. |
