The emission of volatiles from the surface and subsurface of planetary bodies can provide fundamental knowledge concerning their formation, evolution, and structure. There are a variety of physical processes that shape the structural, kinematic and thermal behavior of the released material.
Cool ($approx 10^4$ K), dense material permeates the hot ($approx 10^6$ K), tenuous solar corona in form of coronal condensations, for example prominences and coronal rain. As the solar atmosphere evolves, turbulence can drive mixing between the condensations and the surrounding corona, with the mixing layer exhibiting an enhancement in emission from intermediate temperature ($approx 10^5$ K) spectral lines, which is often attributed to turbulent heating within the mixing layer.
We present the Red Unknowns: Bright Infrared Extragalactic Survey (RUBIES) providing JWST/NIRSpec spectroscopy of red sources selected across ∼150 arcmin2 from public JWST/NIRCam imaging in the UDS and EGS fields. The novel observing strategy of RUBIES offers a well-quantified selection function. The survey has been optimised to reach high (>70%) spectroscopic completeness for bright and red (F150W−F444W>2) sources that are very rare.
We present statistics on the polarization properties of whistler waves in the solar wind down to 0.05 AU (10.75 RS) using data from Parker Solar Probe’s first 17 encounters. These properties were previously uncharacterized due to a technical issue affecting one component of the search‐coil magnetometer after Encounter 1.
Low, marine clouds cool the Earth system, reflecting sunlight back to space. Low cloud response to environmental change is a key uncertainty in future climate projections. It is especially uncertain how much warming amplification will occur due to tropical cumulus feedback. A potentially important feedback modulator is the ability for cumulus to cluster through mesoscale circulations. Janssens et al.
A primary characteristic of solar flares is the efficient acceleration of electrons to nonthermal deka-keV energies. While hard X-ray (HXR) observation of bremsstrahlung emission serves as the key diagnostic of these electrons. In this study, we investigate the time evolution of flare-accelerated electrons using the warm-target model.
Context. Widespread solar energetic particle (SEP) events remain poorly understood phenomena in space weather. These events are often linked to coronal mass ejections (CMEs) and their shocks, but the mechanisms governing their global particle distribution remain debated. The 13 March 2023 event is particularly notable as a widespread SEP event associated with an exceptionally fast interplanetary shock.
Validation of satellite-derived essential climate variable (ECV) datasets requires comparison against independent measurements. These independent measurements, which include ground-based, airborne, and other non-satellite-based measurements, are typically the product of a different measurement system and may include some contribution from models.
Electrostatic electron cyclotron harmonic (ECH) waves have been analyzed using different satellite data. However, single‐mission studies prevent a systematic understanding of the emissions in Earth’s magnetosphere. We perform a comprehensive survey of ECH waves using observations from Van Allen Probes, Arase, and MMS satellites spanning over 2012–2023.
Context. The past decade has seen a rise in the use of machine learning methods in the study of young stellar evolution. This trend has led to a growing need for a comprehensive database of young stellar objects (YSOs) that goes beyond survey-specific biases and can be employed for training, validating, and refining the physical interpretation of machine learning outcomes.
