Three new exoplanet systems from the Dispersed Matter Planet Project
J. R. Barnes, C. A. Haswell, Z. O. B. Ross +7
We present a radial velocity analysis of three bright, low-activity stars identified by the Dispersed Matter Planet Project (DMPP). We use a Bayesian framework to compare purely Ke…
The Dispersed Matter Planet Project Sample -- Detection limits, Occurrence Rates and New Planets
Matthew R. Standing, John R. Barnes, Carole A. Haswell +8
DMPP is a radial-velocity survey that aims to detect planets around stars exhibiting anomalous activity signatures, consistent with the presence of close-in evaporating planets. He…
Lessons learned from the detection of wide companions by radial velocity and astrometry
Fabo Feng, Guang-Yao Xiao, Hugh R. A. Jones +3
The detection and constraint of the orbits of long-period giant planets is essential for enabling their further study through direct imaging. Recently, it has been highlighted that…
The CARMENES search for exoplanets around M dwarfs. Characterization of the nearby ultra-compact multiplanetary system YZ Ceti
S. Stock, J. Kemmer, S. Reffert +38
The nearby ultra-compact multiplanetary system YZ Ceti consists of at least three planets. The orbital period of each planet is the subject of discussion in the literature due to s…
A compact multi-planet system around a bright nearby star from the Dispersed Matter Planet Project
D. Staab, C. A. Haswell, J. R. Barnes +7
The Dispersed Matter Planet Project targets stars with anomalously low Ca II H&K chromospheric emission. High precision, high cadence radial velocity measurements of the F8V star H…
MuSCAT2 multicolour validation of TESS candidates: an ultra-short-period substellar object around an M dwarf
H. Parviainen, E. Palle, M. R. Zapatero-Osorio +37
We report the discovery of TOI 263.01 (TIC 120916706), a transiting substellar object (R = 0.87 RJup) orbiting a faint M3.5~V dwarf (V=18.97) on a 0.56~d orbit. We set out to deter…
Precision radial velocities of 15 M5 - M9 dwarfs
J. R. Barnes, J. S. Jenkins, H. R. A. Jones +8
We present radial velocity measurements of a sample of M5V-M9V stars from our Red-Optical Planet Survey, ROPS, operating at 0.65-1.025 micron. Radial velocities for 15 stars, with…
Status of the Calan-Hertfordshire Extrasolar Planet Search
James S. Jenkins, Hugh R. A. Jones, Patricio Rojo +10
In these proceedings we give a status update of the Calan-Hertfordshire Extrasolar Planet Search, an international collaboration led from Chile that aims to discover more planets a…
ROPS: A New Search for Habitable Earths in the Southern Sky
J. R. Barnes, J. S. Jenkins, H. R. A. Jones +7
We present the first results from our Red Optical Planet Survey (ROPS) to search for low mass planets orbiting late type dwarfs (M5.5V - M9V) in their habitable zones (HZ). Our obs…
The Calan-Hertfordshire Extrasolar Planet Search
J. S. Jenkins, H. R. A. Jones, K. Gozdziewski +7
The detailed study of the exoplanetary systems HD189733 and HD209458 has given rise to a wealth of exciting information on the physics of exoplanetary atmospheres. To further our u…
