In this talk, we discuss how this enables us to more accurately determine the physical properties of Sun-like stars, to understand the nature of surface convection and its connection to activity, and to better determine the properties of planets around cool stars. Indeed, such sensitive photometric &quot;flicker&quot; variations are now within reach for thousands of stars, and we estimate that upcoming missions like TESS will enable such measurements for ~100 000 stars. We present recent results that tie “flicker” to granulation and enable a simple measurement of stellar surface gravity with a precision of 0.1 dex. We use this, together and solely with two other simple ways of characterizing the stellar photometric variations in a high quality light curve, to construct an evolutionary diagram for Sun-like stars from the Main Sequence on towards the red giant branch. We discuss further work that correlates “flicker” with stellar density, allowing the application of astrodensity profiling techniques used in exoplanet characterization to many more stars. We also present results suggesting that the granulation of F stars must be magnetically suppressed in order to fit observations. Finally, we show that we may quantitatively predict a star's RV jitter using our evolutionary diagram, permitting the use of discovery light curves to help prioritize follow-up observations of transiting exoplanets.<br /> <br /> <br /> '''11/10'''<br /> <br /> Recent results:<br /> <br /> [http://phys.org/news/2014-11-birth-planets-revealed-astonishing-alma.html HL Tau imaging from ALMA]<br /> <br /> Jun Yang &amp; Dorian Abbott on their latest paper: [http://arxiv.org/abs/1411.0540 Water Trapping on Tidally Locked Terrestrial Planets Requires Special Conditions].<br /> <br /> <br /> '''11/17'''<br /> <br /> Philae's landing on Comet 67P<br /> <br /> [http://arxiv.org/abs/1411.3724 The MINERVA project for automated RV planet-finding]<br /> <br /> [http://arxiv.org/abs/1411.1754 Prospects for transit observations with JWST]<br /> <br /> <br /> '''11/24'''<br /> <br /> Recent arXiv papers<br /> <br /> <br /> '''12/1'''<br /> <br /> Recent papers:<br /> <br /> [http://arxiv.org/pdf/1411.7412.pdf Luger &amp; Barnes - extreme water loss on planets around M dwarfs]<br /> <br /> [http://arxiv.org/pdf/1411.7660.pdf de Mooij et al. - ground-based transit observations of 55 Cnc e]<br /> <br /> [http://arxiv.org/pdf/1411.7761.pdf Chavez et al. - Kepler circumbinary planet stability]<br /> <br /> [http://arxiv.org/pdf/1411.5066.pdf Batygin et al. - Chaotic disintegration of the inner solar system]<br /> <br /> [http://arxiv.org/pdf/1411.7028.pdf Kipping et al. - Kepler's exo-moons (or the lack thereof)]<br /> <br /> [http://arxiv.org/pdf/1411.7404.pdf Deming et al. - Spitzer secondary eclipse observations &amp; instrumental systematics]</div> Mbedell https://cosmo.uchicago.edu/exoplanet_reading/index.php/Summer_2014 Summer 2014 2014-10-20T22:42:34Z <p>Fabrycky: Created page with &quot;7/7 Arxiv.org recent papers 7/21 Arxiv.org recent papers: the bulk compositions of super-Earths; a transiting planet near the snow line; and the 1% of scientific publishing...&quot;</p> <hr /> <div>7/7<br /> <br /> Arxiv.org recent papers<br /> <br /> <br /> 7/21<br /> <br /> Arxiv.org recent papers: the bulk compositions of super-Earths; a transiting planet near the snow line; and the 1% of scientific publishing <br /> <br /> <br /> 8/4, 8/18<br /> <br /> Arxiv.org recent papers<br /> <br /> <br /> 8/25<br /> <br /> Courtney Dressing (Harvard)<br /> <br /> Frequency of potentially habitable planets around M dwarfs from Kepler data<br /> <br /> <br /> 9/15<br /> <br /> Arxiv.org recent papers</div> Fabrycky https://cosmo.uchicago.edu/exoplanet_reading/index.php/Spring_2014 Spring 2014 2014-10-20T22:09:54Z <p>Fabrycky: Created page with &quot;Go to Current_schedule 4/7/14 Meeting at Northwestern, all day.
