Sodium Brightening of (3200) Phaethon Near Perihelion

Qicheng Zhang, Karl Battams, Quanzhi Ye +2

Sunskirting asteroid (3200) Phaethon has been repeatedly observed in STEREO HI1 imagery to anomalously brighten and produce an antisunward tail for a few days near each perihelion…

Io's Optical Aurorae in Jupiter's Shadow

Carl Schmidt, Mikhail Sharov, Katherine de Kleer +13

Decline and recovery timescales surrounding eclipse are indicative of the controlling physical processes in Io's atmosphere. Recent studies have established that the majority of Io…

The Optical Aurorae of Europa, Ganymede and Callisto

Katherine de Kleer, Zachariah Milby, Carl Schmidt +2

The tenuous atmospheres of the Galilean satellites are sourced from their surfaces and produced by a combination of plasma-surface interactions and thermal processes. Though thin,…

Doppler-Shifted Alkali D Absorption as Indirect Evidence for Exomoons

Carl Schmidt

Sodium and potassium signatures in transiting exoplanets can be challenging to isolate from the stellar absorption lines. Here, these challenges are discussed in the framework of S…

Lunar Volatiles and Solar System Science

Parvathy Prem, Ákos Kereszturi, Ariel N. Deutsch +38

Understanding the origin and evolution of the lunar volatile system is not only compelling lunar science, but also fundamental Solar System science. This white paper (submitted to…

Sodium and Potassium Signatures of Volcanic Satellites Orbiting Close-in Gas Giant Exoplanets

Apurva V. Oza, Robert E. Johnson, Emmanuel Lellouch +12

Extrasolar satellites are generally too small to be detected by nominal searches. By analogy to the most active body in the Solar System, Io, we describe how sodium (Na I) and pota…
