CFHTWIR-Oph 98 b
CFHTWIR-Oph 98 B is a substellar object, either an exoplanet or a sub-brown dwarf that orbits CFHTWIR-Oph 98 A, a M-type brown dwarf. The pair form a binary system. The primary is a M9–L1 dwarf and the secondary is an L dwarf with a spectral type of L2–L6. Both spectral types are estimated from photometry. The pair is separated by 200 astronomical units and has a low gravitational binding energy. The primary Oph 98A has a spectrum taken in 2012 with VLT/ISAAC, matching a spectral type of M9.75 and from Spitzer photometry and near-infrared photometry it is surrounded by a class II disk. This disk has a mass of 0.135 according to a study using SED-modelling.
