Low levels of sulphur dioxide contamination of Venusian phosphine spectra

Jane S. Greaves, Paul B. Rimmer, Anita M. S. Richards +7

New analysis is presented of the 1.1 mm wavelength absorption lines in Venus' atmosphere that suggested the presence of phosphine. We retrieve a sulphur dioxide observation from th…

Recovery of Spectra of Phosphine in Venus' Clouds

Jane S. Greaves, Anita M. S. Richards, William Bains +7

We recover PH3 in the atmosphere of Venus in data taken with ALMA, using three different calibration methods. The whole-planet signal is recovered with 5.4σ confidence using Venus…

On the Robustness of Phosphine Signatures in Venus' Clouds

Jane S. Greaves, William Bains, Janusz J. Petkowski +8

We published spectra of phosphine molecules in Venus' clouds, following open-science principles in releasing data and scripts (with community input leading to ALMA re-processing, n…

Re-analysis of Phosphine in Venus' Clouds

Jane S. Greaves, Anita M. S. Richards, William Bains +7

We first respond to two points raised by Villanueva et al. We show the JCMT discovery spectrum of PH3 can not be re-attributed to SO2, as the line width is larger than observed for…

Phosphine Gas in the Cloud Decks of Venus

Jane S. Greaves, Anita M. S. Richards, William Bains +16

Measurements of trace-gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbor, Venus, has cloud decks that are temperat…

Micrometer-Sized Water Ice Particles for Planetary Science Experiments: Influence of Surface Structure on Collisional Properties

Sabrina Gärtner, Bastian Gundlach, Thomas F. Headen +7

Models and observations suggest that ice-particle aggregation at and beyond the snowline dominates the earliest stages of planet-formation, which therefore is subject to many labor…

Ground-based detection of a cloud of methanol from Enceladus: When is a biomarker not a biomarker?

E. Drabek-Maunder, J. Greaves, H. J. Fraser +2

Saturn's moon Enceladus has vents emerging from a sub-surface ocean, offering unique probes into the liquid environment. These vents drain into the larger neutral torus in orbit ar…

Processing of analogues of plume fallout in cold regions of Enceladus by energetic electrons

A. Bergantini, S. Pilling, B. G. Nair +2

Enceladus, a small icy moon of Saturn, is one of the most remarkable bodies in the solar system. This moon is a geologically active object, and despite the lower temperatures on mo…

Experimental Studies on the Aggregation Properties of Ice and Dust in Planet-Forming Regions

Daniel Heißelmann, Helen J. Fraser, Jürgen Blum

To reveal the formation of planetesimals it is of great importance to understand the collision behavior of the dusty and icy aggregates they have formed from. We present an experim…

Microgravity experiments on the collisional behavior of Saturnian ring particles

Daniel Heißelmann, Jürgen Blum, Helen J. Fraser +1

In this paper we present results of two novel experimental methods to investigate the collisional behavior of individual macroscopic icy bodies. The experiments reported here were…
