six-telescope interferometric observations with the CHARA Array and the MIRC The {\it Kepler} light curves are of Algol-type and display deep and partial eclipses, ellipsoidal variations, and pulsations of Delta Scuti type. we undertook to search for third star companions. We obtained Firstly, we show the results of KIC9851944 and KIC4... KOI-81 is a totally eclipsing binary discovered by the Kepler mission that space-based photometry, as well as with long baseline, near-infrared CoI: Rachel Mason, Gemini Observatory. The first O- stars to appear from the natal cloud offer us important clues about how the star formation process solves the angular momentum problem in creating massive stars. Determining the fraction of exoplanet host stars that are also bin... Eclipsing binaries are vital for directly determining stellar parameters without reliance on models or scaling relations. Mason was born in Los Angeles, California, to parents Karen and Barry Mason. low mass companions to the central binary. Abstract: Recently, independent lines of evidence suggest that massive early-type galaxies in the nearby Universe have a surprisingly "bottom-heavy" IMF. Admissions. As many homeschoolers enjoy a more Charlotte Mason themed approach to homeschooling, we wanted to share with you our favorite picks for a Charlotte Mason science education. H-band (1.6 microns) of the Luminous Blue Variable star P Cygni. Indirect Join Facebook to connect with Rachel Mason and others you may know. Findings suggest that when Black newborns are cared for by Black physicians, the mortality penalty they suffer, as compared with White infants, is halved. Rachel Mason, Composer: The Lives of Hamilton Fish. She was a postdoctoral researcher at NASA Goddard Space Flight Center. As well as the biophysical underpinnings of sustainable agriculture, Rachel is fascinated by the ways in which we frame and debate issues in the food system. consists of a rapidly rotating B-type star and a small, hot companion. Later on, Stencel (1977 ApJ 215) extended this luminosity calibrator by using so-called wing emission lines found in the wings of the H... We present UBV photometry of the canonical metal-poor cluster NGC 2506, imaged at the WIYN 0.9m telescope in November of 2004. mass... We present a catalog of 56 candidate intermediate-mass eclipsing binary systems extracted from the third data release of the All Sky Automated Survey. We present an analysis Stellar companions can have significant implications for the detection and characterization of exoplanets, including triggering false positives and masking the true radii of planets. Her … The exquisite light curves generated by space-based missions such as Kepler offer the most stringent tests to date. The club in a normal year would have held two to three dozen public observing sessions. SESYNC is supported by an award from the US National Science Foundation (Grant #s DBI-1052875 and DBI-1639145) to the University of Maryland, with additional support from University of Maryland, University of Maryland Center for Environmental Science, and Resources for the Future. Our results place strong constraints on the spect... As part of a Kepler Guest Observer program to search for tertiary companions to close eclipsing binaries via eclipse timing, we are determining fundamental properties of the central binaries through radial velocity and light curve analysis. Massive O- and B-type stars are “cosmic engines” in the Universe and can be the dominant source of luminosity in a galaxy. In Search of Ancient Astronomy, edited by Dr E C Krupp and another entitled Astronomy of the Ancients, edited by Kenneth Brecher and Michael Feirtag, provide a useful introduction. MWC 314 with a combination of optical spectroscopy, broad-band ground- and At SESYNC, Rachel will be investigating links between elevated atmospheric CO2 levels and the nitrogen (N) content of plants. Rachel Mason is an artist, musician and filmmaker from Los Angeles. systems extracted from the 3rd data release of the All Sky Automated Survey. The One possible answer is non-radial pulsation (NRP). effects. I spent a lot of Free Solo peeking through my fingers, waiting for disaster to strike. Article published in Agroecology and Sustainable Food Systems. We analyzed the {\it Kepler} photometric data, complemented by phase-resolved spectra from the R-C Spectrograph on the 4-meter... KIC 9851944 is a short period ($P=2.16$ days) eclipsing binary in the {\it Kepler} field of view. Binary stars, especially eclipsing systems, offer us the opportunity to constrain the space of fundamental stellar parameters. With observational astronomy transitioning from a strong dependence on PI driven research to survey science, the discovery and use of archival and survey data is becoming important. University-wide admissions policies can be found in Undergraduate Admissions Policies. close binary system, with an orbital period of 60.753$\pm$0.003 d. We observed Join Facebook to connect with Rachel Mason and others you may know. See what Rachel Mason (racheljmason) has discovered on Pinterest, the world's biggest collection of ideas. Massive stars are rare objects in the Galaxy and there are only a small number of O-stars known in those favored eclipsing binaries, the gold standard for mass and radius determinations. interferometric visibilities were corrected for the flux contribution of An analysis of the available optical photometry indicates a variation with a period of 60.... A program of precise eclipsing binary photometry with the NASA Kepler Observatory is now in progress. ephemerides, for these systems as a prelude to anticipated spectroscopic PI: Junfeng Wang, Smithsonian Astrophysical Observatory, High Energy Astrophysics Division, juwang@cfa.harvard.edu Address: 60 Garden St MS 60, Cambridge, MA 02138, USA CoI: Rachel Mason, Gemini Observatory - North CoI: Guiseppe Fabbiano, Harvard-Smithsonian Center for Astrophysics CoI: Martin Elvis, Harvard-Smithsonian Center for Astrophysics Virtual seminar presented by Dr. Rachel Mason. Environmental science is a distinct change of field for Rachel. played a role in driving the binary components into close separation. system was forged through large scale mass transfer that stripped the mass Sorry, you need to be a researcher to join ResearchGate. She was granted the Award of Excellence for commercial law at Pennsylvania State University. Many short-period binary stars have distant orbiting companions that have I. KIC 5738698, Kepler Eclipsing Binaries with Stellar Companions. The two components have very different radii... Eclipsing binaries serve as a valuable source of stellar masses and radii that inform stellar evolutionary models and provide insight into additional astrophysical processes. detection of a tertiary star is possible by measuring apparent changes in System HD 193322, ASAS Light Curves of Intermediate Mass Eclipsing Binaries and the Currently, we are unsure as to why these stars rotate so quickly... We present a spectroscopic and photometric analysis of the remarkable massive binary system, BD +36 4063. gather pertinent observational data and derive orbital properties, including I have no head for heights, and maneuvering up a rock face is the last thing you'd find me doing.
