Brown dwarfs are the critical link between the products of stellar and planetary formation pathways; hence, their population properties and compositions can inform on the likelihood of either formation history. In particular, multiplicity is a direct outcome of formation, yet it is challenging to measure it in a consistent way, since each binary detection technique is sensitive to a different range of separations and mass ratios.
In this talk, I will present results from a volume-limited spectroscopic sample, including a new binary fraction straddling the hydrogen-burning minimum mass, which separates stars from brown dwarfs. I will discuss future directions for a comprehensive characterization of both the statistical distributions of the population of multiple systems and the fundamental properties of their individual components as a function of age. These are crucial steps to identify spectroscopic signatures of formation.
Christopher Chambers-Ju ’04, visiting assistant professor at the College of the Holy Cross, will give a talk titled “Mobilizing Teachers: The Political Strategies of Mass Member Organizations in Latin America.”
Chambers-Ju received his Ph.D. in political science from the University of California, Berkeley, in 2017. His research examines the politics of education through a focus on teachers’ unions. Studying the cases of Argentina, Colombia and Mexico, he examines why some teachers take to the streets while others form an organized voting bloc, with distinct relationships to political parties. By focusing on teachers, he seeks to shed light on broader dynamics of education policy-making and political change in contemporary Latin America.
This event is free and open to the public and is sponsored by the Department of Political Science at Amherst College with funding from the Lurcy Endowment and the Lamont Funds.
Selected Video Works presents four videos by Mariah Garnett made between 2010 and 2014. These works represent the early cornerstones of her experimental documentary practice. In all four films, the relationship between subject and filmmaker is foregrounded, calling into question the power dynamics at play in representational art practices.
“Garbage, The City, And Death” uses a Fassbinder text to reframe a real-life relationship between long-lost siblings as a romantic rivalry. It was Garnett’s first attempt to mix theatricality with a real relationship between herself and her subject.
“Picaresques” takes its inspiration from Lieutenant Nun, the autobiography of a transgender conquistador at the turn of the 17th century as its inspiration and abruptly becomes a portrait of Garnett’s own friendship with a 9-year-old tomboy from Santa Monica. It is an attempt to look to the past and future for heroes of a similar gender to the artist’s own.
“Encounters I May or May Not Have Had with Peter Berlin” moves through phases of idolization, anxiety ending in a touchdown in reality in a conversation between the artist and Berlin himself. This is the first film in which Garnett used impersonation as a strategy for representing her subject.
Finally, “Full Burn” marks a shift in Garnett’s practice away from overtly queer themes to the geopolitical. It is a portrait of four U.S. war veterans who have continued to use their own physicality to earn a living, three as stunt men and one as a massage therapist. It is a meditation on masculine duty, trauma and re-enactment.
Mariah Garnett is an artist and filmmaker who lives and works in Los Angeles. She holds a B.A. in American civilization and an M.F.A. from California Institute of the Arts in film/video. In 2019 she was awarded a Guggenheim Fellowship in Film/Video for her feature film, Trouble, which premiered at the London Film Festival and was named one of the best documentaries of the year by Sight + Sound. Her work has screened and been exhibited internationally at venues including The New Museum, The Hammer Museum, Tate Belfast, REDCAT, SFMoMA and her exhibiting gallery, Commonwealth + Council. She is a MacDowell Fellow, and her work has been featured in Bomb, Artforum and Reverse Shot.
