What you need is to massively increase the albedo (ability to reflect light) of the planet, as well as the planet's ability to shed heat.

To increase albedo, you could also use gases such as sulphur dioxide, or even just tiny particulates (which will also increase the frequency of reflective clouds, especially saltwater particulates). I reccommend researching global cooling . However, I don't know enough about the subject to know how likely it would be to reduce the temperature of a planet so cose to an orange giant to 63 degrees, but hey, it's science fiction!

I remember one source saying that detectors had measured that the amount sunight reching the UK had gone down by as much as 65% due to global cooling caused by human activities.

Note: Global warming is strong enough to override global cooling, so don't feel too relieved about climate change. Global cooling is just intense enough to make it look like the predictions made by climate scientists are incorrect, therefore causing climate change scepticism.
