(cba:news) bk lyn figures, and stars (Joe Patterson) [2012-11-20T22:30:07Z]


Here are the scanned figures for the paper I sent earlier today. A couple are slightly botched, but anyway they should suffice for comments.

I'm awfully keen to carry out this type of analysis for the other ER UMa stars, especially V1159 Ori since it's perfectly placed now and available to all hemispheres. We had a good campaign 20 years ago, and have a lot more firepower today!

The ER UMa class has a thing for 9 hr right ascension: ER UMa, BK Lyn, RZ LMi, and DI UMa. Half the class! It's a tad too early in the season to get serious about these guys, but you might want to pick your favorite (I especially recommend the latter two) and start obtaining some time series. Then pick up the pace in a month's time. In general I'd say BK Lyn and ER UMa are slightly lower priority, because we covered them so thoroughly in the 2011-12 season.

It is not, however, too early for T Pyx! Also 9 hr RA, but because the interest there is simpler (the possible existence and waveform of an orbital signal), there is no need for very long time series - a few hours per night is fine. It's time to see how the eruption has treated our precious pre-eruption orbital signal. I bet a few weeks of coverage from our powerful southern outposts (South Africa/Chile/NZ/AU will nail this quite nicely... and will separate that paper, too (17 years in the making), from the glue of my desk.

Finally, I'd like to vigorously push PX And. Still very much in season, and likely another one of these two-brands-of-superhump characters. I'll be pushing a lot of Sex stars (its class) in the next months.

I've been neglecting the dwarf novae. But Enrique has kept that flame going, and the Galaxy has furnished us with some pretty interesting ones in the last few weeks/months. I hope to catch up with all this activity over the holiday.

So... V1159 Ori, T Pyx, PX And, and maybe some other ER UMa star. That's my short list for now. For a change, no DQ Her stars.... although they're always good targets when conditions are poor.
