Notes for OGLE-TR-3

update: 7 November 2003

The planets:

• Detection method: Transit (confirmation by Radial Velocity)
• Basic data:

  Name:	OGLE-TR-3 b
  M.sini:	~ 0.5 MJ ?
  Radius:	1.4 RJ
  Semi-major axis:	~ 0.025 AU
  Orbital period:	1.1899 d.
  Eccentricity:	-
  Omega (deg):	-
  T_peri (JD-2450000):	2060.22765
  Inclination:	~ 90 deg ?

• Remarks:
  3 Jun. 26: Konacki et al (2003a) interpret the transit as a probable blend by a background eclipsing binary
  3 Mar. 03: Possible planet, to be confirmed (Dreizler et al 2003).
  Konacki et al (2003) interpret OGLE-TR-3 b as a grazing star.
