Quantifying the Bulk Density of Southern Delta Aquariid Meteoroids: Insights from the Canadian Automated Meteor Observatory
Arazi Pinhas, Zbyszek Krzeminski, Denis Vida +1
Physical properties of ten millimeter-sized meteoroids from the Southern Delta Aquariids (SDA) shower are derived using optical observations from the Canadian Automated Meteor Obse…
A Physical Survey of Meteoroid Streams: Comparing Cometary Reservoirs
Nicolas Buccongello, Peter G. Brown, Denis Vida +1
In this work, we present an optical survey of mm-sized meteoroids using the Canadian Automated Meteor Observatory's (CAMO) mirror tracking system. The system tracks meteors to magn…
Constraining Stellar Photospheres as an Essential Step for Transmission Spectroscopy of Small Exoplanets
Benjamin V. Rackham, Arazi Pinhas, Dániel Apai +29
Transmission spectra probe the atmospheres of transiting exoplanets, but these observations are also subject to signals introduced by magnetic active regions on host stars. Here we…
An optical transmission spectrum of the ultra-hot Jupiter WASP-33b. First indication of AlO in an exoplanet
C. von Essen, M. Mallonn, L. Welbanks +4
There has been increasing progress toward detailed characterization of exoplanetary atmospheres, in both observations and theoretical methods. Improvements in observational facilit…
HO abundances and cloud properties in ten hot giant exoplanets
Arazi Pinhas, Nikku Madhusudhan, Siddharth Gandhi +1
Transmission spectroscopy of exoplanets has the potential to provide precise measurements of atmospheric chemical abundances, in particular of hot Jupiters whose large sizes and hi…
Physical properties and optical-infrared transmission spectrum of the giant planet XO-1b
John Southworth, J. Tregloan-Reed, A. Pinhas +3
We present ten high-precision light curves of four transits in the XO-1 planetary system, obtained using , , , redshifted H, and filters. We use these to measur…
Retrieval of planetary and stellar properties in transmission spectroscopy with Aura
Arazi Pinhas, Benjamin V. Rackham, Nikku Madhusudhan +1
Transmission spectroscopy provides a powerful probe of the atmospheric properties of transiting exoplanets. To date, studies of exoplanets in transit have focused on inferring thei…
Evidence for a Dayside Thermal Inversion and High Metallicity for the Hot Jupiter WASP-18b
Kyle Sheppard, Avi M. Mandell, Patrick Tamburo +4
We find evidence for a strong thermal inversion in the dayside atmosphere of the highly irradiated hot Jupiter WASP-18b (T, ) based on emission spectrosco…
On Signatures of Clouds in Exoplanetary Transit Spectra
Arazi Pinhas, Nikku Madhusudhan
Transmission spectra of exoplanetary atmospheres have been used to infer the presence of clouds/hazes. Such inferences are typically based on spectral slopes in the optical deviant…
Efficiency of Planetesimal Ablation in Giant Planetary Envelopes
Arazi Pinhas, Nikku Madhusudhan, Cathie Clarke
Observations of exoplanetary spectra are leading to unprecedented constraints on their atmospheric elemental abundances, particularly O/H, C/H, and C/O ratios. Recent studies sugge…
Complete history of the observable 21-cm signal from the first stars during the pre-reionization era
Anastasia Fialkov, Rennan Barkana, Arazi Pinhas +1
We present the first complete calculation of the history of the inhomogeneous 21-cm signal from neutral hydrogen during the era of the first stars. We use hybrid computational meth…
