a young K7eV-type classical T Tauri star ...
A companion candidate is found 0.7â€²â€² west of GQ Lup (Fig. 1). By comparison with the primary (K=7.0960.020 mag, 2MASS),we got Ks = 13.1 Â±0.1 mag for the companion candidate with aperture photometry after subtracting the primary.

*********************

Whoa! The 'planet' is 13th mag, quite a bit brighter than I'd thought it would be at any wavelength. Even at less than an arc-second from the primary, today's big scopes should be able to pull some further spectral data. Neat HR diagram. Am I reading it correctly regarding the high luminosity of newly born super Jovians?
