Highly depleted alkali metals in Jupiter's deep atmosphere
Ananyo Bhattacharya, Cheng Li, Sushil K. Atreya +12
Water and ammonia vapors are known to be the major sources of spectral absorption at pressure levels observed by the microwave radiometer (MWR) on Juno. However, the brightness tem…
Jupiter's Temperature Structure: A Reassessment of the Voyager Radio Occultation Measurements
Pranika Gupta, Sushil K. Atreya, Paul G. Steffes +12
The thermal structure of planetary atmospheres is an essential input for predicting and retrieving the distribution of gases and aerosols, as well as the bulk chemical abundances.…
Ultracold Neutral Plasmas
Thomas C. Killian, Y. C. Chen, P. Gupta +6
Ultracold neutral plasmas are formed by photoionizing laser-cooled atoms near the ionization threshold. Through the application of atomic physics techniques and diagnostics, these…
Absorption Imaging and Spectroscopy of Ultracold Neutral Plasmas
T. C. Killian, Y. C. Chen, P. Gupta +6
Absorption imaging and spectroscopy can probe the dynamics of an ultracold neutral plasma during the first few microseconds after its creation. Quantitative analysis of the data, h…
Using Absorption Imaging to Study Ion Dynamics in an Ultracold Neutral Plasma
C. E. Simien, Y. C. Chen, P. Gupta +5
We report optical absorption imaging of ultracold neutral plasmas.Images are used to measure the ion absorption spectrum, which is Doppler-broadened. Through the spectral width, we…
