TraMoS: V. Updated ephemeris and multi-epoch monitoring of the hot Jupiters WASP-18Ab, WASP-19b, and WASP-77Ab(star)
(EDP Sciences, 2020)
We present 22 new transit observations of the exoplanets WASP-18Ab, WASP-19b, and WASP-77Ab, from the Transit Monitoring in the South project. We simultaneously model our newly collected transit light curves with archival ...
The short rotation period of hi'iaka, haumea's largest satellite
(The American Astronomical Society, 2016-12)
Hi’iaka is the larger outer satellite of the dwarf planet Haumea. Using relative photometry from the Hubble Space.Telescope and Magellan and a phase dispersion minimization analysis, we have identified the rotation period ...
The short rotation period of Hi’Iaka, Haumea’s largest satellite
(IOP Publishing Ltd., 2016)
Hi'iaka is the larger outer satellite of the dwarf planet Haumea. Using relative photometry from the Hubble Space Telescope and Magellan and a phase dispersion minimization analysis, we have identified the rotation period ...
Spiral waves triggered by shadows in transition disks
(IOP Publishing, 2016)
Circumstellar asymmetries such as central warps have recently been shown to cast shadows on outer disks. We investigate the hydrodynamical consequences of such variable illumination on the outer regions of a transition ...
A gap in the planetesimal disc around HD 107146 and asymmetric warm dust emission revealed by ALMA
(Oxford University Press, 2018)
While detecting low mass exoplanets at tens of au is beyond current instrumentation, debris discs provide a unique opportunity to study the outer regions of planetary
systems. Here we report new ALMA observations of the ...
The CARMENES search for exoplanets around M dwarfs Characterization of the nearby ultra-compact multiplanetary system YZ Ceti
(EDP Sciences, 2020)
Context. The nearby ultra-compact multiplanetary system YZ Ceti consists of at least three planets, and a fourth tentative signal. The orbital period of each planet is the subject of discussion in the literature due to ...
Orbital and spectral characterization of the benchmark T-type brown dwarf HD19467B
(EDP Science, 2020)
Context. Detecting and characterizing substellar companions for which the luminosity, mass, and age can be determined independently is of utter importance to test and calibrate the evolutionary models due to uncertainties ...
