Multiple Star Systems Observed with Corot and Kepler
Multiple star systems observed with CoRoT and Kepler John Southworth Astrophysics Group, Keele University, Staffordshire, ST5 5BG, UK Abstract. The CoRoT and Kepler satellites were the first space platforms designed to perform high-precision photometry for a large number of stars. Multiple systems dis- play a wide variety of photometric variability, making them natural benefactors of these missions. I review the work arising from CoRoT and Kepler observations of multiple sys- tems, with particular emphasis on eclipsing binaries containing giant stars, pulsators, triple eclipses and/or low-mass stars. Many more results remain untapped in the data archives of these missions, and the future holds the promise of K2, TESS and PLATO. 1 Introduction The CoRoT and Kepler satellites represent the first generation of astronomical space missions capable of large-scale photometric surveys. The large quantity – and exquisite quality – of the data they pro- vided is in the process of revolutionising stellar and planetary astrophysics. In this review I highlight the immense variety of the scientific results from these concurrent missions, as well as the context provided by their precursors and implications for their successors. CoRoT was led by CNES and ESA, launched on 2006/12/27,and retired in June 2013 after an irre- trievable computer failure in November 2012. It performed 24 observing runs, each lasting between 21 and 152days, with a field of viewof 2×1.3◦ ×1.3◦, obtaining light curves of 163000 stars [42]. Kepler was a NASA mission, launched on 2009/03/07and suffering a critical pointing failure on 2013/05/11. It observed the same 105deg2 sky area for its full mission duration, obtaining high-precision light curves of approximately 191000 stars. -
Magnetism, Dynamo Action and the Solar-Stellar Connection
Living Rev. Sol. Phys. (2017) 14:4 DOI 10.1007/s41116-017-0007-8 REVIEW ARTICLE Magnetism, dynamo action and the solar-stellar connection Allan Sacha Brun1 · Matthew K. Browning2 Received: 23 August 2016 / Accepted: 28 July 2017 © The Author(s) 2017. This article is an open access publication Abstract The Sun and other stars are magnetic: magnetism pervades their interiors and affects their evolution in a variety of ways. In the Sun, both the fields themselves and their influence on other phenomena can be uncovered in exquisite detail, but these observations sample only a moment in a single star’s life. By turning to observa- tions of other stars, and to theory and simulation, we may infer other aspects of the magnetism—e.g., its dependence on stellar age, mass, or rotation rate—that would be invisible from close study of the Sun alone. Here, we review observations and theory of magnetism in the Sun and other stars, with a partial focus on the “Solar-stellar connec- tion”: i.e., ways in which studies of other stars have influenced our understanding of the Sun and vice versa. We briefly review techniques by which magnetic fields can be measured (or their presence otherwise inferred) in stars, and then highlight some key observational findings uncovered by such measurements, focusing (in many cases) on those that offer particularly direct constraints on theories of how the fields are built and maintained. We turn then to a discussion of how the fields arise in different objects: first, we summarize some essential elements of convection and dynamo theory, includ- ing a very brief discussion of mean-field theory and related concepts. -

A Triply Eclipsing System with Intrinsically Variable Red Giant Component A
Title : will be set by the publisher Editors : will be set by the publisher EAS Publications Series, Vol. ?, 2013 HD181068: A TRIPLY ECLIPSING SYSTEM WITH INTRINSICALLY VARIABLE RED GIANT COMPONENT A. Derekas1, T. Borkovits21, 3, J. Fuller4, D. Huber5 and H. Lehmann6 Abstract. We present the analysis of HD 181068 which is one of the first triply eclipsing triple system discovered. Using Kepler photome- try, ground based spectroscopic and interferometric measurements, we determined the stellar and orbital parameters of the system. We show that the oscillations observed in the red giant component of the system are tidally forced oscillations, while one of the most surprising results is that it does not show solar-like oscillations. 1 Introduction The ultraprecise and continous photometry of Kepler space telescope led to great discoveries not just in the field of exoplanets but in stellar astrophysics too. Among others, it opened a new era in the investigation of multiple star systems, such as dis- coveries of the first triply eclipsing triple systems, KOI-126 (Carter et al. (2011)) and HD 181068 (Derekas et al. (2011)). The special geometry of these triply (or mutually) eclipsing triple systems, enables us fast and easy determination of fur- ther characteristics that otherwise could only be studied with great effort on a long time-scale. Here we present the analysis of the triply eclipsing hierarchical triple sys- tem HD 181068 based on Kepler photometry, ground based high-resolution spec- troscopy and interferometry. HD 181068 has a magnitude of V = 7.1 and a dis- tance of about 250 pc (van Leeuwen (2007)). -

Planet Hunters1 (Fischer Et Al
draft version May 31, 2012 Planet Hunters: Assessing the Kepler Inventory of Short Period Planets Megan E. Schwamb1,2,3,Chris J. Lintott4,5, Debra A. Fischer6, Matthew J. Giguere6, Stuart Lynn5,4, Arfon M. Smith5,4, John M. Brewer6, Michael Parrish5, Kevin Schawinski2,3,7, and Robert J. Simpson4 [email protected] ABSTRACT We present the results from a search of data from the first 33.5 days of the Kepler science mission (Quarter 1) for exoplanet transits by the Planet Hunters citizen science project. Planet Hunters enlists members of the general public to visually identify tran- sits in the publicly released Kepler light curves via the World Wide Web. Over 24,000 volunteers reviewed the Kepler Quarter 1 data set. We examine the abundance of ≥ 2 R⊕ planets on short period (< 15 days) orbits based on Planet Hunters detections. We present these results along with an analysis of the detection efficiency of human classifiers to identify planetary transits including a comparison to the Kepler inventory of planet candidates. Although performance drops rapidly for smaller radii, ≥ 4 R⊕ Planet Hunters ≥ 85% efficient at identifying transit signals for planets with periods less than 15 days for the Kepler sample of target stars. Our high efficiency rate for simulated transits along with recovery of the majority of Kepler ≥4R⊕ planets suggest suggests the Kepler inventory of ≥4 R⊕ short period planets is nearly complete.

What more can I say. If you have not made plans for a road trip, you can help out at HRPO. All who are going on a road trip be prepared to share pictures and experiences at the September meeting. BRAS has lost another member, Bart Bennett, who joined BRAS after Chris Desselles gave a talk on Astrophotography to the Cajun Clickers Computer Club (CCCC) in January of 2016, Bart became the President of CCCC at the same time I became president of BRAS. The Clickers are shocked at his sudden death via heart attack. Both organizations will miss Bart. His obituary is posted online here: http://www.rabenhorst.com/obituary/sidney-barton-bart-bennett/ Last month’s meeting, at LIGO, was a success, even though there was not much solar viewing for the public due to clouds and rain for most of the afternoon. BRAS had a table inside the museum building, where Ben and Craig used material from the Night Sky Network for the public outreach.
