NASA's TESS Mission Reaches for Cooler Planets

 

Abstract

Abstract: Launched in 2018, TESS - NASA’s latest planet hunting mission - has greatly exceeded expectations. It has brought about the discovery of hundreds of transiting exoplanets, and thousands more awaiting confirmation. Though TESS' observing strategy is biased towards short-period planets, after nearly six years of observations TESS-discovered exoplanets with period in the tens-to-hundreds of days are being confirmed at an accelerating pace. In this talk, I will describe how the TESS Single Transit Planet Candidate Working Group searches for long-period planet candidates in TESS observations, and how we validate or confirm those that are true planets. I will present the science cases we aim to address through these discoveries, including finding increasingly temperate planets amenable to follow-up studies, probing planet occurrence on the outskirts of M dwarf systems, and improving our understanding of circumbinary planet populations and formation. I will highlight a few systems of interest, and outline directions for the future of this effort..

The NSF National Radio Astronomy Observatory and NSF Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NSF NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NSF NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NSF NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NSF NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The U.S. National Science Foundation (U.S. NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
