The dust condensation sequence in red supergiant stars [PDF]
Astronomy & Astrophysics, 2009 Context: Red super-giant (RSG) stars exhibit significant mass loss through a slow and dense wind. They are often considered to be the more massive counter parts of Asymptotic Giant Branch (AGB) stars. While the AGB mass loss is linked to their strong pulsations, the RSG are often only weakly variable.

Interacting supernovae from photoionization-confined shells around red supergiant stars [PDF]
Nature, 2014 Betelgeuse, a nearby red supergiant, is a runaway star with a powerful stellar wind that drives a bow shock into its surroundings. This picture has been challenged by the discovery of a dense and almost static shell that is three times closer to the star than the bow shock and has been decelerated by some external force.

Measuring surface magnetic fields of red supergiant stars [PDF]
Astronomy & Astrophysics, 2017 Context.Red supergiant (RSG) stars are very massive cool evolved stars. Recently, a weak magnetic field was measured at the surface ofαOri and this is so far the only M-type supergiant for which a direct detection of a surface magnetic field has been reported.Aims.By extending the search for surface magnetic field in a sample of late-type supergiants ...

Geophysical Research Letters, Volume 50, Issue 18, 28 September 2023., 2023 Abstract Giant icebergs release cold, fresh meltwater as they drift, perturbing the physical conditions of the surface ocean. This study uses satellite‐derived sea surface salinity and temperature measurements to explore the physical impact of supergiant iceberg A68A between September 2020 and June 2021.

Giant breast phyllodes tumor with silent thromboembolism: A case report
Cancer Reports, Volume 6, Issue 9, September 2023., 2023 Abstract Background Phyllodes tumor (PT) is a solid fibroepithelial breast lesion with proliferation of stromal and epithelial elements, usually presents with a rapidly expanding feature. Venous thromboembolism (VTE) have been reported to increase the burden in terms of mortality and morbidity of malignant tumor, and associate with worsened survival ...

First Observations With a GNSS Antenna to Radio Telescope Interferometer
Radio Science, Volume 58, Issue 8, August 2023., 2023 Abstract We describe the design of a radio interferometer composed of a Global Navigation Satellite Systems (GNSS) antenna and a Very Long Baseline Interferometry radio telescope. Our eventual goal is to use this interferometer for geodetic applications including local tie measurements.

Burial and Denudation Alter Microbial Life at the Bottom of the Hypo‐Critical Zone
Geochemistry, Geophysics, Geosystems, Volume 24, Issue 6, June 2023., 2023 Abstract How subsurface microbial life changed at the bottom of the kilometers‐deep (hypo) Critical Zone in response to evolving surface conditions over geologic time is an open question. This study investigates the burial and exhumation, biodegradation, and fluid circulation history of hydrocarbon reservoirs across the Colorado Plateau as a window ...

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 8, August 2022., 2022 Abstract Extensive regions of yellow and white (“bleached”) sandstones within the terrestrial Jurassic red bed deposits of the Colorado Plateau reflect widespread interaction with subsurface reduced fluids which resulted in the dissolution of iron‐oxide grain coatings.
