In the present paper I want to tell of my impressions about the world of research in astrophysics, which I know from close observation. I see with certain pessimism the actual state of astrophysics, as well as of other sciences with similar problems. There are many charms in the profession, as many charms as in love, but not when they are in the

Synchrotron emission from jets produced by X-ray binaries can be detected at optical and infrared (IR) frequencies. I show that optical/IR colour-magnitude diagrams of the outbursts of nine X-ray binaries successfully separate thermal disc emission from non-thermal jet emission, in both black hole and neutron star sources. A heated single
