Also, the spot at 21h 00m 07s, +50d 13m 04s can be seen quite well. <br /> <br /> [[Image:Halloween.jpg]]<br /> <br /> --[[User:Skennedy|Skennedy]] 05:51, 29 October 2008 (PDT) I found some information about a star previously known in LDN 981. Here's the abstract from the Astrophysical Journal.<br /> <br /> '''ABSTRACT''' We characterize the small- and large-scale environment of the young star V1331 Cygni with high-resolution HST WFPC2 and Digitized Sky Survey images. In addition to a previously known outer dust ring (≈ in diameter), the WFPC2 scattered light image reveals an inner dust ring for the first time. This ring has a maximum radius of ≈ and is possibly related to a molecular envelope. Large-scale optical images show that V1331 Cyg is located at the tip of a long dust filament linking it to the dark cloud LDN 981. We discuss the origin of the observed dust morphology and analyze the object's relation to its parent dark cloud LDN 981. Finally, based on recent results from the literature, we investigate the properties of V1331 Cyg and conclude that in its current state the object does not show sufficient evidence to be characterized as an FU Ori object.<br /> <br /> <br /> --[[User:Jbutchart|JenniferButchart]] 10:49, 29 October 2008 (PDT) I got on ADS today and found the same article (by Quanz, S. P.; Apai, D.; Henning, Th.) titled Dust Rings and Filaments around the Isolated Young Star V1331 Cygni. It is the same one as Shana found. I do believe these are the points they identified:<br /> <br /> [[Image:Jen.JPG]]<br /> <br /> --[[User:Sandy|Sandy]] 13:22, 30 October 2008 (PDT) This is sandy's test comment.<br /> <br /> <br /> --[[User:Jbutchart|JenniferButchart]] 05:29, 31 October 2008 (PDT) I just read that entire article on astro-ph (found here: [http://lanl.arxiv.org/PS_cache/astro-ph/pdf/0610/0610786v1.pdf astro-ph]) and it says V1331 Cyngi is, mostly likely, the only star that has formed in LDN 981 (it formed in isolation). However, they stated that stars may form along the filaments of the cloud since it it undergoing a graviational collapse.<br /> <br /> --[[User:AlixHolcomb|AlixHolcomb]] 11:26, 31 October 2008 (PDT)So I know it was like hours ago, but Spuck wanted someone to post about our video confrence. So I decided too. We established that the Oil City team needs to start making SED's and color color plots. I'm currently trying to conquer FITS liberator so that our color composite images turn out not as pixilated and a little less generic RBG. I'm sorta getting the handle of everything.

Here's the abstract from the Astrophysical Journal.<br /> <br /> '''ABSTRACT''' We characterize the small- and large-scale environment of the young star V1331 Cygni with high-resolution HST WFPC2 and Digitized Sky Survey images. In addition to a previously known outer dust ring (≈ in diameter), the WFPC2 scattered light image reveals an inner dust ring for the first time. This ring has a maximum radius of ≈ and is possibly related to a molecular envelope. Large-scale optical images show that V1331 Cyg is located at the tip of a long dust filament linking it to the dark cloud LDN 981. We discuss the origin of the observed dust morphology and analyze the object's relation to its parent dark cloud LDN 981. Finally, based on recent results from the literature, we investigate the properties of V1331 Cyg and conclude that in its current state the object does not show sufficient evidence to be characterized as an FU Ori object.<br /> <br /> <br /> --[[User:Jbutchart|JenniferButchart]] 10:49, 29 October 2008 (PDT) I got on ADS today and found the same article (by Quanz, S.

In addition to a previously known outer dust ring (≈ in diameter), the WFPC2 scattered light image reveals an inner dust ring for the first time. This ring has a maximum radius of ≈ and is possibly related to a molecular envelope. Large-scale optical images show that V1331 Cyg is located at the tip of a long dust filament linking it to the dark cloud LDN 981. We discuss the origin of the observed dust morphology and analyze the object's relation to its parent dark cloud LDN 981.

Here's the abstract from the Astrophysical Journal.<br /> <br /> '''ABSTRACT''' We characterize the small- and large-scale environment of the young star V1331 Cygni with high-resolution HST WFPC2 and Digitized Sky Survey images. In addition to a previously known outer dust ring (≈ in diameter), the WFPC2 scattered light image reveals an inner dust ring for the first time. This ring has a maximum radius of ≈ and is possibly related to a molecular envelope. Large-scale optical images show that V1331 Cyg is located at the tip of a long dust filament linking it to the dark cloud LDN 981. We discuss the origin of the observed dust morphology and analyze the object's relation to its parent dark cloud LDN 981. Finally, based on recent results from the literature, we investigate the properties of V1331 Cyg and conclude that in its current state the object does not show sufficient evidence to be characterized as an FU Ori object.<br /> <br /> <br /> --[[User:Jbutchart|JenniferButchart]] 10:49, 29 October 2008 (PDT) I got on ADS today and found the same article (by Quanz, S. P.; Apai, D.; Henning, Th.) titled Dust Rings and Filaments around the Isolated Young Star V1331 Cygni. It is the same one as Shana found. I do believe these are the points they identified:<br /> <br /> [[Image:Jen.JPG]]<br /> <br /> --[[User:Sandy|Sandy]] 13:22, 30 October 2008 (PDT) This is sandy's test comment.<br /> <br /> <br /> --[[User:Jbutchart|JenniferButchart]] 05:29, 31 October 2008 (PDT) I just read that entire article on astro-ph (found here: [http://lanl.arxiv.org/PS_cache/astro-ph/pdf/0610/0610786v1.pdf astro-ph]) and it says V1331 Cyngi is, mostly likely, the only star that has formed in LDN 981 (it formed in isolation). However, they stated that stars may form along the filaments of the cloud since it it undergoing a graviational collapse.<br /> <br /> --[[User:AlixHolcomb|AlixHolcomb]] 11:26, 31 October 2008 (PDT)So I know it was like hours ago, but Spuck wanted someone to post about our video confrence. So I decided too. We established that the Oil City team needs to start making SED's and color color plots. I'm currently trying to conquer FITS liberator so that our color composite images turn out not as pixilated and a little less generic RBG. I'm sorta getting the handle of everything. I&quot;ll post later.<br /> <br /> --[[User:Jbutchart|JenniferButchart]] 21:07, 1 November 2008 (PDT) Alix, I posted about the video conference [with screen shot] under the video conference section right after we hung up.<br /> <br /> --[[User:Rachele|Rachele]] 10:43, 4 November 2008 (PST) Jenni and I collected everyone's points of interest.

We believe that there may be more and I will have my astronomy students looking this coming week during class.
