=Stars and Planets Lunch and Talks (every Monday)=

We meet weekly to talk about stars & planets, both ours and others. (When Monday is a holiday, we meet on Tuesdays.)

IfA email alias: //** splat "at" the_usual_ifa_domain **//


 * Current format (version 4.1):**

//** * Research talk ** = a "semi-informal" talk about what you have been doing lately. Since it's work in progress, it's expected that multiple sessions in a row will involve the same topic, esp. for students.// //Also, you should include one slide called **"Something I Don't Understand"** to share (at least) one problem, obstacle, etc. that you have run into, and perhaps not solved yet. Finally, for research that is discovery-oriented, everyone in the audience should remember to be appropriately mindful about (not) broadcasting stuff that is still cooking.//

//** * MIPOW ** = Most Important Paper of the Week (presumably from astro-ph but not necessarily).// //Please circulate by Friday midday so everyone can read it before the meeting. Also, be sure to include one slide called **"Why This is the MIPOW"** in your presentation.// //A potential list of papers is here but feel free to choose from elsewhere too. If you are seeking suggestions, please don't hesitate to ask.//

//1. Choose a *science* white paper from the list on the National Academy web site available at// [|//http://sites.nationalacademies.org/BPA/BPA_050603//]//. (Do not select from the technology/policy/etc lists available elsewhere, though some of them would make interesting reading in your spare time.)//
 * //Here are the guidelines for the Dedacal Survey paper discussions://**

//2. Provide a modest (~20 min) review & critical assessment of the topic: background, history, goals, key questions, scope, recommendations, positives, negatives, commentary, etc. Feel free to draw info & figures from elsewhere to make your points.//

//3. You're encouraged to avoid choosing papers on which you're an author (to avoid intellectual myopia) but it's up to you. Please choose your paper carefully - there is a wide range in quality, scope, focus & (especially) fluffiness. Not all of them are suitable for an interesting & illuminating group discussion.//

//4. No repeat presentations on the same white paper.//

=Rules for One-Plot Lunch=

- Everyone presents 1 plot from a relatively recent paper/preprint (not your own work nor a previous MIPOW). If you're looking for ideas, an incomplete list of various recent papers resides at https://www.evernote.com/pub/m_c_liu/MIPOW, or feel free to ask around.

- Please send your plot to the designated organizer, including key paper info (lead author & title) on your slide.

- Each person will give a <=4 minute explanation of the plot and the science behind it, with some brief additional time for questions.

- At the end, we'll vote on the "best" plot, as judged by our unspecified sense of most interesting/impactful science and accompanying presentation.
