 Okay, it's Sunday, just after lunchtime, I'm driving down to the airport for Cool Stars 20. It's the last big meeting I have this year, and I'm giving a talk to a pretty big audience, so I gotta make sure that lands right. I need to practice today and tomorrow. I've been prepping for this meeting for a few weeks, writing my talk, getting some work done, but my mental prep begins here, begins on my drive to the airport. This is the moment when I start getting my game face on. After I've left home, the suitcases are in the car, until I land back home, I'll be in work mode. This is going to be a good meeting. I love Boston. It's a great town. We'll be mostly over at Boston University. There's a ton of amazing astronomers who work in Boston. Friends of mine I haven't seen in a long time. It's going to be fun. Now we'll move on to the last talk of this session before the coffee break. Rotating Stars from Kepler. Observed with Gaia DR2 by James Davenport, University of Washington. That's for that. Okay, we'll jump right in. The long list of superlatives that you can use to describe three models failed to reproduce a number of observational properties, like mass stars and new constants. Most of these problems actually could be solved by the hypothesis, and be careful there, the hypothesis that they are inflated, possibly by magnetic fields. Talk right down here. It's a calcium K-line. The black curve here is in a rotational phase, which the star is more inactive. Plenary talk, and it was announced there, white dwarfs were a thing. They've been discovered. We've broken the T-dwarf boundary. My name is Sarah Jane Schmidt. I'm a postdoc at the Leibniz Institute for Astrophysics in Potsdam, and I study the smallest stars. I'm most interested in their magnetic fields and how they evolve over time, and how they cause flares and other sorts of activity. My name is Brett Morris. I work on stellar activity in Exoplanet. My 10-second advice to you is that if you're a grad student and you're going to a conference, don't go to every talk. I'm Sarah Ballard. I'm at MIT, and I'm here to learn about how to figure out the ages of M-dwarfs. Hi, my name is Stephanie Douglas. I'm an NSF fellow at the Harvard Smithsonian Center for Astrophysics, and I study stellar rotation in open clusters, both how it correlates with magnetic activity and multiplicity. Good morning. We are here in Boston, Massachusetts for the Cool Stars 20, the Cool Stars 20 meeting. So it's Wednesday, the middle day of the week, and today's schedule is a full slate of talks in the morning with a coffee break, and then in the afternoon instead of the talkable sessions we've been having all week, they have time for excursions. For those of us who have been to Boston a bunch, a bunch of us are going to hide out in a coffee shop and get some work done. So it's Wednesday. I gave a talk on Monday, the first day of the conference, and I posted a full video of that talk on this channel a couple days ago. So if you want to see that talk, go check out that video. I'll put the link below. One thing the conference organizers have done this time, which is really cool, is they've put these little images on your bed. So I put one of the graphs from my talk, and on the other side I put one of the graphs that represents the gender survey that we've been doing, which I've talked about on this channel before, and I'll put another link to below. Cool Stars was my very first meeting, Cool Stars 14, way back in 2006, was my first like real astronomy conference. So it's always good to come back. It is a cool meeting to talk at. If you go to the double AS meeting, which I showed in January on this channel, if you get one of the big talks, the plenary talks, you could be speaking to a couple of thousands of astronomers. It's a big audience. But if you get one of the normal sort of session talks like I did, and then you're talking to like 50, maybe 100. The main session in Cool Stars is about 500 people, which is a really big meeting for being such a small focused topic. Oh yeah, one of the things that started becoming a tradition at the Cool Stars meetings is swag. A tradition now in the last few ones is like coffee mugs or tea mugs. So I think I have four of these so far from various meetings, and they're usually pretty nice. I'm Mark Veit, and I find out what small stars are made of. Hi, I'm Julie Skinner, and I'm measuring distances and looking for planets around the very smallest stars. Hi, I'm Carl Schmidt. I'm a research scientist at Boston University, and I study escaping planetary atmospheres. Hi, my name is Phil Muirhead. I'm an assistant professor of astronomy here at Boston University, and I'm on the scientific organizing committee for this conference. And I decided to do a presentation on tests, the smallest stars that tests will observe and search for planets. Some thoughts about how these two different scenarios could influence what you're observing. Yeah, absolutely. Both the majority of the measurements in the past 40 years have either been high spectral resolution over a very narrow spectral band pass, or they've been integrated over a fairly broad band pass. And similarly with the extreme launch of other images that we've obtained from SDOAA, in particular the 94 ancient channel. Two other points before we do the picture one. And James and I will edit ourselves in seamless. Hi, I'm Serge Dietrich. I work at Carnegie's Department of Rest and Magnetism. I think the cool thing about cool stars is to just see the complexity evolve in the field. My name is Meredith Joyce. I am currently at Dartmouth, though I just defended three weeks ago, and that will be changing soon. What this poster is on is optimizing mixing length calibrations for systems which are sufficiently well constrained. Hi, I'm Dr. Rachel Rotenbacher, and I image the surfaces of active stars with a variety of different techniques. Hi, my name is Laura Mallorca, and I'm here at Cool Stars for my brown dwarfs, because I'm interested in studying the diversity of exoplanet atmospheres in a very similar to giant planets. Is that what I came to say? Mic drop. And now for a true cool stars tradition, the banquet. It's like we're there. It's been another good week. We've got cool stars. It's been a great cool star. You were on the S&C, right? I was on the S&C. Thank you for a great meeting. Oh, thank you so much. The banquet is always one of the biggest highlights of the meeting. They always have good food. They always pick a cool location. And the most exciting part is they tell you when the next cool stars and where it will be. So in two years we will be in Toulouse, France, which is really cool. I'm on a 9 a.m. flight back to Seattle. It's been a good meeting.
