dc.description.abstract |
OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of
magnitude. The only exception to this may be at minimum light when the AGN activity is so low that the host galaxy may make
quite a considerable contribution to the photometric intensity of the source. Such a dip or a fade in the intensity of OJ 287 occurred
in 2017 November, when its brightness was about 1.75 mag lower than the recent mean level. We compare the observations
of this fade with similar fades in OJ 287 observed earlier in 1989, 1999, and 2010. It appears that there is a relatively strong
reddening of the B − V colours of OJ 287 when its V-band brightness drops below magnitude 17. Similar changes are also seen
in V − R, V − I, and R − I colours during these deep fades. These data support the conclusion that the total magnitude of the host
galaxy is V = 18.0 ± 0.3, corresponding to MK = −26.5 ± 0.3 in the K-band. This is in agreement with the results, obtained
using the integrated surface brightness method, from recent surface photometry of the host. These results should encourage us
to use the colour separation method also in other host galaxies with strongly variable AGN. In the case of OJ 287, both the host
galaxy and its central black hole are among the biggest known, and its position in the black hole mass–galaxy mass diagram lies
close to the mean correlation. |
