Aphelion Cloud Belt Phase Function Investigations with Mars Color Imager (MARCI)
Brittney A. Cooper, John E. Moores, Joseph M. Battalio +4
This paper constrains the scattering phase function of water ice clouds (WICs) found within Mars' Aphelion Cloud Belt (ACB), determined from orbit by processing publicly available…
Visibility and Line-Of-Sight Extinction Estimates in Gale Crater during the 2018/MY34 Global Dust Storm
Christina L. Smith, John E. Moores, Mark Lemmon +4
Northern line-of-sight extinction within Gale Crater during the 2018 global dust storm was monitored daily using MSL's Navcam. Additional observations with Mastcam (north) and Navc…
Constraints on Mars Aphelion Cloud Belt Phase Function and Ice Crystal Geometries
Brittney A. Cooper, John E. Moores, Douglas J. Ellison +4
This study constrains the lower bound of the scattering phase function of Martian water ice clouds (WICs) through the implementation of a new observation aboard the Mars Science La…
Opening PANDORA's box: APEX observations of CO in PNe
L. Guzman-Ramirez, A. I. Gomez-Ruiz, H. M. J. Boffin +5
Context. Observations of molecular gas have played a key role in developing the current understanding of the late stages of stellar evolution. Aims. The survey Planetary nebulae AN…
UV production of methane from surface and sedimenting IDPs on Mars in light of REMS data and with insights for TGO
John E. Moores, Christina L. Smith, Andrew C. Schuerger
This paper refines model predictions for the production of methane from UV-irradiated interplanetary dust particles (IDPs) now that the Rover Environmental Monitoring Station (REMS…
Penitentes as the origin of the bladed terrain of Tartarus Dorsa, Pluto
John E. Moores, Christina L. Smith, Anthony Toigo +1
Penitentes are ablative features observed in snow and ice that, on Earth, are characterized by regular cm to tens of cm spaced bowl-shaped depressions whose edges grade into tall s…
Abundances in Galactic Bulge planetary nebulae from optical, ultraviolet and infrared observations
Christina L. Smith, Albert A. Zijlstra, Krzysztof M. Gesicki +1
Iron suffers from high levels of depletion in the highly ionized environments of planetary nebulae, making the direct determination of undepleted elemental iron abundances difficul…
Possible ground fog detection from SLI imagery of Titan
Christina L. Smith, Brittney A. Cooper, John E. Moores
Titan, with its thick, nitrogen-dominated atmosphere, has been seen from satellite and terrestrial observations to harbour methane clouds. To investigate whether atmospheric featur…
ALMA reveals sunburn: CO dissociation around AGB stars in the globular cluster 47 Tucanae
Iain McDonald, Albert A. Zijlstra, Eric Lagadec +15
ALMA observations show a non-detection of carbon monoxide around the four most luminous asymptotic giant branch (AGB) stars in the globular cluster 47 Tucanae. Stellar evolution mo…
A molecular line survey of a sample of AGB stars and planetary nebulae
Christina L. Smith, Albert A. Zijlstra, Gary A. Fuller
A millimeter molecular line survey of three carbon-rich AGB stars and two oxygen-rich planetary nebulae has been carried out over the frequency range 80.5-115.5 GHz. Sixty eight di…
Zinc abundances of planetary nebulae
Christina L. Smith, Albert A. Zijlstra, Harriet L. Dinerstein
Zinc is a useful surrogate element for measuring Fe/H as, unlike iron, it is not depleted in the gas phase media. Zn/H and O/Zn ratios have been derived using the [Zn IV] emission…
A new HCN maser in IRAS 15082-4808
C. L. Smith, A. A. Zijlstra, G. A. Fuller
We have identified a new vibrational HCN maser at 89.087 GHz in the asymptotic giant branch (AGB) star IRAS 15082-4808, a maser which is thought to trace the innermost region of an…
