Table B.2

Main physical parameters of the GoHam b candidate protoplanet in the model.

Input parameters

Cext 2.5 × 10-23 ( 2.5 × 10-24) Mid-IR dust cross-section in cm2/H
p b 4.25 Position of GoHam b in cross cut Fig. 3 (”)
Δv 1.7 Width of the 13CO line in km/s
Tex 16 CO excitation temperature in K

Output parameters

r b 155 ± 31 Clump radius in AU
M b 0.95 ± 0.19 (9.5±1.9) Clump mass in Jupiter masses1
n b 7.0 ± 1.4 × 106 (7.0 ± 1.4 × 107) Clump density in cm-3

Notes.Error bars result from the uncertainty in adjusting the model and on the distance to GoHam (the latter being dominant). The values in parenthesis correspond to the case when Cext is a factor of 10 smaller than the ISM value, i.e., Cext = 2.5 × 10-24 cm2/H.
