Revision as of 02:16, 7 February 2011

Wiki

Wiki: http://coolwiki.ipac.caltech.edu/ Everyone can VIEW it, but you can only EDIT if you have an account. Send your student names/emails to me (Luisa) and I'll set them up. My creating an account for you will result in an automatic mail being sent to you which might get caught in your spam filter. I will let you know the default password; you can reset it when you log in.

Basic wiki philosophy: two main sections -- "worksheet style" in "research tools" and "working areas for teams" in "current research". there are links between the two spaces, and with some experience here playing around with the pages, you will see that there is a different tone between the two sections.

In order to set up pages for each of the teams, I need a name for each team. This doesn't have to be a name like "Fred" -- it can be related to the science you're planning on doing. Check out the pages for previous groups here: http://coolwiki.ipac.caltech.edu/index.php/Current_Research_Projects

Cool Cosmos

Cool Cosmos website (public face of the program) http://coolcosmos.ipac.caltech.edu/cosmic_classroom/teacher_research/index.shtml The individual team pages will be linked with the rest here: http://coolcosmos.ipac.caltech.edu/cosmic_classroom/teacher_research/allprog.shtml once I have a proposal title from each of the teams. The individual teacher pages will be linked with the rest here: http://coolcosmos.ipac.caltech.edu/cosmic_classroom/teacher_research/people/ once I get a chance to set them up (and I'll excerpt something from the AAS worksheet stuff you send us).

Luisa's tutorial on star formation from cool cosmos

APT

APT download http://spider.ipac.caltech.edu/staff/laher/apt

Previous Proposals

All of the previous proposals are online, linked from the teams' Cool Cosmos page. All of the programs are listed here: http://coolcosmos.ipac.caltech.edu/cosmic_classroom/teacher_research/allprog.shtml and if you go to any of the team pages, you'll see lots of things, including a link to the proposal. BUT PLEASE NOTE that up until last year, all of these past proposals were OBSERVING proposals and you are writing an ARCHIVAL proposal. The 2010 class was also archival proposals.

Policies and Procedures

As always, please don't hesitate to send email if you have questions. I'm a little frantic this week, so I might be delayed in responding. If you need faster help than that, please check the Cool Cosmos site -- I collected all of the policy/procedure stuff here: http://coolcosmos.ipac.caltech.edu/cosmic_classroom/teacher_research/polproc/ some of it is a tiny bit dated, and it's on my list to update this, sorry.

More background on Star Formation

Notes from a U of Oregon lecture on star formation ... not as good as Luisa's lecture notes but a good launching point ... http://abyss.uoregon.edu/~js/ast122/lectures/lec13.html

A more detailed explanation of Star Formation from a textbook. There's more math here than we'll need. File:SF.pdf --CJohnson 11:05, 1 February 2011 (PST)


--- From Marcella

BRC 34 1 proposal to study by Garmire, nothing on SIMBAD

BRC 36 3 articles on ADS two are on star formation but none on SIMBAD

BRC 38 1 article by Choudhury which identified 45 YSO's

BRC 31 nothing on both

BRC 27 Chauhan observed BR 27 and came up with some YSO candidates and a catalog(?) entry on SIMBAD.

BRC27

07h04m07.8s

-11d16m43s

ADS: Chauhan; Simbad: 14 entries (I checked them, not all seem to be on this exact area)

Images: the Aladdin Sky Atlas (DSS2 & Simbad) shows the image fairly bright where the B & W is dark. Kicking in the IRAS data only makes 5 IR targets show up, plus the cloud near the bottom of the image.

Where are all the targets & YSOs that are mentioned by Chauhan? Chauhan abstract (2009) “Triggered star formation and evolution of T-Tauri stars in and around bright-rimmed clouds.” From Chauhan’s data tables 4 & 6 I gleaned the following nuggets of information: table4.dat 85 133 Dereddened magnitude, colors, age and mass of the YSOs associated with the BRCs; Last entry from table 4 and Table 6 each say this: Cl II YSO class (meta.code.class) (CLASS_CODE)

Coordinates for this cloud come up as: 07 03 58.7 -11 23 19 IRAS 07016-1118 slightly south and to the right of the main image of BRC27

From data Table 6: IRAC photometric magnitudes of the disk bearing candidates in BRCs 2, 27 and 13/14 (are we interested in examining this?)


BRC31

20h50m43.4s

+44d21m53s

Busy field; Cloud in center of Aladin Applet image.(right on these coordinates) surrounded by Emission line stars, HH, and radio sources, and an X-ray source. The frame completely fills up when 2MASS is applied.

DSS2 shows a thick cloud. Simbad shows the sources described above.

BRC34

21h32m51.2s

+58d08m43s

0 ADS abstracts; 0 Simbad citations No object listed at (or near) these precise coordinates, however, AllSky Optical images reveal the clouds that were of interest to Lori. Parts of the cloud are labeled. The DSS2.POSSII image reveals 2 star clusters, a Cloud Dark Nebula, and 2 IR sources (one above & slightly to the right of the center of the image) Many hits on 2MASS

BRC36

21h35m32.6s

+57d31m50s

3 results from ADS: 1 abstract, 2 Chandra proposals; 0 results from Simbad, however, Aladin applet Simbad identifies (and IRAS-IRIS reveals) 6 YSO’s, 10 IR sources, 2 Mol Cld, Rf Neb, Br Neb, Dk Neb, stars in nebulae, and stars in clouds.

This looks like an interesting field. Lots going on (too much?) ADS: Garmire and Getman are both proposing to use Chandra to study this area. (x-rays)

BRC38 (is this SFO 38?)

21h40m02.2s

+58d20m31s

Triggered Star Formation and Young Stellar Population in Bright-rimmed Cloud SFO 38 by Choudhury, Rumpa; Mookerjea, Bhaswati; Bhatt, H. C.

They have identified 45 YSO’s in this area, although I only counted 19 in the image I was able to pull up. They studied the area with a variety of instruments and wavelengths (including Spitzer). This seems like a fairly comprehensive study.
