From jop at astro.columbia.edu Wed Oct 9 10:39:52 2024 From: jop at astro.columbia.edu (Joe Patterson) Date: Wed, 9 Oct 2024 10:39:52 -0400 Subject: (cba:news) recent news... Message-ID: Hi CBAers, I've persuaded Matt Wood (Texas A&M - Commerce) to join me with the duties of "heading" (with Jonathan's help, and maybe Enrique's) the CBA. Matt is very experienced with CVs, mostly from the theory side but plenty familiar with observation as well. I think he's been observing DQ Her for quite a few years. So your data will go to the three of us, at least - as well as in the archive which anyone can access (and AAVSO for that matter). I'm still banging the drums for V1674 Her, despite faintness (18) and a poor sky position. The pulse period continues to shorten, though at a lower rate... and a good value for it now will make it easier to bridge the gap until February, when Hercules comes back. Same goes for DQ Her, though it has no significant off-season uncertainty like V1674 Her. IM Nor and T Pyx are excellent choices now, to try to track their meteoric-at-last-sight period changes. That leaves late-night northern objects - of that, later. joe ____________________________________________________________ Center for Backyard Astrophysics (CBA) mailing lists https://cbastro.org/communications/mailing-lists/ From jop at astro.columbia.edu Wed Oct 9 14:23:25 2024 From: jop at astro.columbia.edu (Joe Patterson) Date: Wed, 9 Oct 2024 14:23:25 -0400 Subject: (cba:news) other candidate stars Message-ID: <37cb2777-b725-49fe-914d-54363d030f62@astro.columbia.edu> To flesh out the previous note: I'm fascinated by V1674 Her and DQ Her because they are the only with a complete pulse-period history since the nova outburst (in the case of DQ Her, I should say "since pulse discovery", but it's possible the pulse was there in the 20 years since the nova outburst, but nobody imagined that such a fast signal could come from a nova - Walker's 1954 discovery was considered shocking. V407 Lupi might be a third such star, but it's still too lightly observed to know. All other IPs have unknown eruption dates, probably centuries or millennia ago. The seasonally-and-magnitude-appropriate IPs are also good targets now - AO Psc, FO Aqr, V1223 Sgr, etc. IM Nor and T Pyx are too -because they are the two stars which appear to be lengthening their Porb at a meteoric rate, consistent with very fast evolution. Not a complete list by any means. Enrique may wish to supplement it - he keeps much better track of the IPs. joe ____________________________________________________________ Center for Backyard Astrophysics (CBA) mailing lists https://cbastro.org/communications/mailing-lists/ From Matt.Wood at tamuc.edu Wed Oct 9 13:17:06 2024 From: Matt.Wood at tamuc.edu (Matt Wood PhD) Date: Wed, 9 Oct 2024 17:17:06 +0000 Subject: (cba:chat) (cba:news) recent news... In-Reply-To: References: Message-ID: <99BDAE8D-F220-41CF-A3DA-728882E7139F@tamuc.edu> Thanks so much, Joe, for thinking of me as worthy of beginning to help with the stewardship of CBA going forward! I?m greatly honored and more than a little intimidated, but mostly very excited to be a part of such an extraordinary collaboration of dedicated astronomers. I look forward to dedicating my time and energy to continue CBA's decades-long legacy of extraordinary success. One of the best things about CBA is the community that you all have built over the years, and I know we can continue to strengthen those ties and continue the CBA scientific productivity. With Joe and Jonathan?s help, I?m working on preparing a proposal to the US National Science Foundation for financial support for the CBA project. If any of you have thoughts on future directions or items that would help you specifically or CBA observers in general, and would like talk via email/texts/WhatsApp/Zoom, please reach out - I would love to get to know you. While this is a change, the mission and overall operation of the CBA isn?t going to change dramatically anytime soon - why mess with success? Joe has promised that he?s going to remain active (i.e., the ?brains?) in the collaboration, but needs someone to help with they day-to-day communications and operations. My email is Matt.Wood at tamuc.edu, and my cell/mobile number is +1 XXX.XXX.XXXX. My university web pages are Here: https://www.tamuc.edu/people/matt-wood/ And here: http://faculty.tamuc.edu/mwood/ (Both need updating, of course). That?s all I can think of at this time. Again I look forward to getting to know you all and working with you going forward. Cheers, Matt -- Matt A.
