The K2 M67 Study: Precise Mass for a Turnoff Star in the Old Open Cluster M67
Eric L. Sandquist, David W. Latham, Robert. D. Mathieu +8
We present a study of the bright detached eclipsing main sequence binary WOCS 11028 (Sanders 617) in the open cluster M67. Although the binary has only one eclipse per orbital cycl…
Extremely precise age and metallicity of the open cluster NGC 2506 using detached eclipsing binaries
E. Knudstrup, F. Grundahl, K. Brogaard +10
Accurate stellar parameters of stars in open clusters can help constrain models of stellar structure and evolution. Here we wish to determine the age and metallicity content of the…
Multiple Transits during a Single Conjunction: Identifying Transiting Circumbinary Planetary Candidates from TESS
Veselin B. Kostov, William F. Welsh, Nader Haghighipour +10
We present results of a study on identifying circumbinary planet candidates that produce multiple transits during one conjunction with eclipsing binary systems. The occurrence of t…
Fast Transit Computation Using Tabulated Stellar Intensities
Donald R. Short, Jerome A. Orosz, Gur Windmiller +1
Limb darkening laws are convenient parameterizations of the stellar intensity center-to-limb variation, and their use is ubiquitous in eclipse and transit modeling. But they are no…
The EBLM project. VII. Spin-orbit alignment for the circumbinary planet host EBLM J0608-59 A/TOI-1338 A
Vedad Kunovac Hodžić, Amaury H. M. J. Triaud, David V. Martin +14
A dozen short-period detached binaries are known to host transiting circumbinary planets. In all circumbinary systems so far, the planetary and binary orbits are aligned within a c…
TOI-1338: TESS' First Transiting Circumbinary Planet
Veselin B. Kostov, Jerome A. Orosz, Adina D. Feinstein +65
We report the detection of the first circumbinary planet found by TESS. The target, a known eclipsing binary, was observed in sectors 1 through 12 at 30-minute cadence and in secto…
