A JWST/MIRI view of κ Andromedae b: Refining its mass, age, and physical parameters

Open Access

Table 6

Age and mass estimates for κ And b from the H-F1140C CMD and isochrones.

Isochrone	Age (Myr)	Mass (M_Jup)	Age(mass) (Myr)
AMES-COND	49 ± 6	17.0 ± 3.4	55 ± 12
ATMO-ceq	42 ± 3	14.5 ± 2.0	45 ± 6
BT-Settl	33 ± 3	14.5 ± 2.0	42 ± 7
Sonora+0.0	39 ± 4	15.3 ± 2.8	40 ± 8
AMES-DUSTY	78 ± 16	24.5 ± 3.7	68 ± 7
Cloud-free	45 ± 5	15.7 ± 2.3	50 ± 8
Cloudy	50 ± 21	18.1 ± 4.8	50 ± 13

Notes. The age and mass were calculated separately using the weighted distribution from the CMD (see text). The age (mass) refers to the age calculated from the mass-age relation given the estimated mass.
