Remarks

06 Apr 2015: Based on the detection of a planet to star reflected flux ratio of 6.0 ± 0.4 x 10-5 and assumed radius 1.9 RJup, Martins et al. 2015 find a planet albedo of 0.5.
19 Oct 2010: Simpson et al. (2010) infer the orbital inclination from the parent star rotation, deriving a planet mass 0.5+0.2-0.1MJ; but the coplanarity of stellar equator with planet orbits is generally not demonstrated.
  • The orbital distance to the star (0.05 AU) was incompatible with theoretical predictions (A. Boss, Science, 287, 360, 1995) and has triggered speculations on orbital migration (Lin et al. 1996, Rasio et al., 1996)
  • No second companion found (Marcy 1996)
  • Further evidence for a planet (Hatzes et al., 1996, 1997): nonradial oscillation modes (l > 4) excluded to explain RV amplitude
  • Further evidence for a planet (Pravdo et al., 1996) from X-ray non detection
  • Planet or M2 star? This question was implicitely raised by a paper by the PTI team claiming that the 51 Peg system may be resolved. See the comment by G. Marcy
  • Circumstellar disk searched for at UKIRT and KECK but not found (Trilling et al. 1999 and 2000)
