Olivia DrakeSeth Redfield, associate professor of astronomy, and Marshall Johnson '11 are the co-authors of an article titled "The Interstellar Medium in the Kepler Search Volume," published in The Astrophysical Journal, Vol. 802, No. 2, July 2015. The article highlights ways scientists are studying the gas and dust in the galaxy near where the Kepler Space Telescope is discovering exoplanets. "Stars, with planets, can interact with the gas surrounding them in interesting ways, like bubbles in a drink, where each of the bubbles is an individual star (perhaps with planets) and the drink is the 'interstellar medium', the gas in between the stars," Redfield explained. In…
Seth Redfield, associate professor of astronomy, and Wilson Cauley, postdoctoral researcher in astronomy, led the effort on a paper titled "Optical hydrogen absorption consistent with a thin bow shock leading the hot Jupiter HD 189733b" accepted for publication in The Astrophysical Journal. Bow shocks are ubiquitous astrophysical phenomena resulting from the supersonic passage of an object through a gas. In this paper, the authors present a robust detection of a time-resolved pre-transit, as well as in-transit, absorption signature around the hot Jupiter exoplanet HD 189733b using high spectral resolution observations of several hydrogen lines. Better knowledge of exoplanet magnetic field strengths is…

Lauren RubensteinIn its most recent meeting, the Board of Trustees conferred tenure on Hari Krishnan, associate professor of dance. He joins seven other faculty members who were awarded tenure earlier this spring. In addition, seven faculty members were promoted to Full Professor: Mary Alice Haddad, professor of government; Scott Higgins, professor of film studies; Tsampikos Kottos, professor of physics; Edward Moran, professor of astronomy; Dana Royer, professor of earth and environmental sciences; Mary-Jane Rubenstein, professor of religion; and Gina Athena Ulysse, professor of anthropology. Brief descriptions of their research and teaching appear below. Associate Professor Krishnan teaches studio- and lecture-based dance courses on Mobilizing Dance: Cinema, the Body, and Culture…
#THISISWHY In this News @ Wesleyan story, we speak with Sam Factor '14, a graduate student in astronomy. Q: Sam, congratulations on completing your master’s thesis in astronomy! We understand you took your first astronomy class in the fall of your senior year at Wesleyan. What was your undergraduate major and how did your late-developing interest in astronomy come about? A: Thank you very much! As an undergrad, I majored in physics and computer science. During the fall of my senior year I took Introductory Astronomy (ASTR 155). I signed up for the course mainly because I wanted an interesting and relatively easy…
On April 29, Sara Seager, Class of 1941 Professor of Planetary Science and Physics at the Massachusetts Institute of Technology, spoke on "The Search for Earth 2.0" at the annual Sturm Memorial Lecture. (Photos by Dat Vu '15) (more…)
Sara Seager, Class of 1941 Professor of Planetary Science and Physics at the Massachusetts Institute of Technology, will deliver the Sturm Memorial Lecture at 8 p.m. on April 29. She will speak in CFA Hall on "The Search for Earth 2.0." Seager is a pioneer in the field of exoplanets, specifically in characterizing the atmospheres and searching for life on those distant worlds. Her talk will address the age-old question: "Are we alone?" (more…)
The Hartford Courant and WNPR both featured stories on Wesleyan's "observatory nights," which began this month. Every Wednesday night at 8 p.m. during the Spring semester, the Van Vleck Observatory will open its doors to the public, rain or shine, for viewing of the sky through telescopes and presentations on the latest space-related research. According to the Courant, Research Assistant Professor of Astronomy Roy Kilgard said the department is seeking to supplement its outreach to groups already interested and involved in science with new sessions for people who may not have a high level of knowledge about space and astronomy. "We're really trying…
Beginning Feb. 4, Wesleyan’s Van Vleck Observatory will open to the public every Wednesday night, rain or shine, for presentations by faculty and students on the latest space-related discoveries, as well as a chance for everyone to view the sky through a telescope, weather permitting. The program will start at 8 p.m. on Wednesdays. Presentations are intended to be accessible to visitors of all ages, although aimed primarily at high school level and above. (more…)
Conor Hunt '16, Trevor Dorn-Wallenstein '15, Girish Duvvuri '17, Coady Johnson '15 represented Wesleyan as student speakers at the 2014 Undergraduate Research Symposium of the Keck Northeast Astronomy Consortium held at Swarthmore College on Nov. 8. A total of five faculty members and eight students from the Astronomy Department, including Greg Schulman '17, currently at Clark University, joined colleagues from around the northeast at this annual event.
Jesse Lieman-Sifry '15 received a $5,000 Undergraduate Directed Campus Scholarship from the Connecticut Space Grant Consortium, funded by NASA. The award will be applied to his financial aid package and support his ongoing research in the Astronomy Department.
Kate CarlisleAssistant professor of Astronomy Meredith Hughes and eight colleagues have found evidence of magnetic fields in stardust – an indication that magnetic fields are important in the process of planetary system formation, according to a new paper in the journal Nature. The discovery is another step in work by Hughes and other astronomers to understand how celestial bodies are formed. It is known that magnetic fields in the “accretion disks” of stars play a dominant role in the star formation process. Using data from an observatory near Bishop, Calf., Hughes and her colleagues were able to spot signs of magnetic…
