Stellar Ages of M Dwarf Hosts of Temperate Sub-Neptunes
Lalitha Sairam, Nikku Madhusudhan
Measuring M dwarf ages is a central challenge in stellar astrophysics. These stars evolve so slowly that isochrone fitting gives little constraint, requiring alternative methods ba…
BEBOP VIII. SOPHIE radial velocities reveal an eccentric, circumbinary brown dwarf
Amaury H. M. J. Triaud, Thomas A. Baycroft, Neda Heidari +18
Circumbinary configurations offer a test of planet formation in an altered environment, where the inner binary has perturbed a protoplanetary disc. Comparisons of the physical and…
BEBOP VII. SOPHIE discovery of BEBOP-3b, a circumbinary giant planet on an eccentric orbit
Thomas A. Baycroft, Alexandre Santerne, Amaury H. M. J. Triaud +21
Planetary systems orbiting close binaries are valuable testing grounds for planet formation and migration models. More detections with good mass measurements are needed. We present…
Evidence for a polar circumbinary exoplanet orbiting a pair of eclipsing brown dwarfs
Thomas A. Baycroft, Lalitha Sairam, Amaury H. M. J Triaud +1
One notable example of exoplanet diversity is the population of circumbinary planets, which orbit around both stars of a binary star system. There are so far only 16 known circumbi…
Characterising M dwarf host stars of two candidate Hycean worlds
Lalitha Sairam, Nikku Madhusudhan
Planetary systems orbiting M dwarf host stars are promising targets for atmospheric characterisation of low-mass exoplanets. Accurate characterisation of M dwarf hosts is important…
BEBOP VI. Enabling the detection of circumbinary planets orbiting double-lined binaries with the DOLBY method of radial-velocity extraction
Lalitha Sairam, Thomas A. Baycroft, Isabelle Boisse +13
Circumbinary planets - planets that orbit both stars in a binary system - offer the opportunity to study planet formation and orbital migration in a different environment compare t…
New methods for radial-velocity measurements of double-lined binaries, and detection of a circumbinary planet orbiting TIC 172900988
Lalitha Sairam, Amaury H. M. J. Triaud, Thomas A. Baycroft +8
Ongoing ground-based radial-velocity observations seeking to detect circumbinary planets focus on single-lined binaries even though over nine in every ten binary systems in the sol…
Radial-velocity discovery of a second planet in the TOI-1338/BEBOP-1 circumbinary system
Matthew R. Standing, Lalitha Sairam, David V. Martin +24
We report the detection of a gas-giant planet in orbit around both stars of an eclipsing binary star system that also contains the smaller, inner transiting planet TOI-1338b. The n…
The need for a public forecast of stellar activity to optimise exoplanet radial velocity detections & transmission spectroscopy
Lalitha Sairam, Amaury H. M. J. Triaud
Advances in high-precision spectrographs have paved the way for the search for an Earth analogue orbiting a Sun-like star within its habitable zone. However, the research community…
BEBOP III. Observations and an independent mass measurement of Kepler-16 (AB) b -- the first circumbinary planet detected with radial velocities
Amaury H. M. J. Triaud, Matthew R. Standing, Neda Heidari +30
The radial velocity method is amongst the most robust and most established means of detecting exoplanets. Yet, it has so far failed to detect circumbinary planets despite their rel…
BEBOP II: Sensitivity to sub-Saturn circumbinary planets using radial-velocities
Matthew R. Standing, Amaury H. M. J. Triaud, João P. Faria +14
BEBOP is a radial-velocity survey that monitors a sample of single-lined eclipsing binaries, in search of circumbinary planets by using high-resolution spectrographs. Here, we desc…
TIC 172900988: A Transiting Circumbinary Planet Detected in One Sector of TESS Data
Veselin B. Kostov, Brian P. Powell, Jerome A. Orosz +86
We report the first discovery of a transiting circumbinary planet detected from a single sector of TESS data. During Sector 21, the planet TIC 172900988b transited the primary star…
