Bolide Infrasound Signal Morphology and Yield Estimates: A Case Study of Two Events Detected by a Dense Acoustic Sensor Network

The Astronomical Journal
Two bolides (2016 June 2 and 2019 April 4) were detected at multiple regional infrasound stations, with many of the locations receiving multiple detections.

The remarkable outflows from the galactic microquasar SS433

, 2016
In this thesis, I present 4 new, high-resolution observations of the Galactic microquasar SS 433, obtained from the Very Long Baseline Array (VLBA). I show that we can resolve the same ejecta in successive observations separated by ∼ 35 d.

In situ single‐spot Rb/Sr cosmochronology of roedderite in the Ribbeck aubrite (asteroid 2024 BX1)

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 768-781, May 2026.
Abstract The mineralogy and textures of several fragments from the Ribbeck aubrite were analyzed using a combination of scanning electron microscopy, electron microprobe analysis, μRaman spectroscopy, and laser ablation inductively coupled reaction cell mass spectrometry (LA‐ICP‐MS/MS).

Orbit, emission spectrum, and photometric analysis of two flickering sporadic fireballs [PDF]

, 2013
We present the observations of two fireballs that exhibit fast and quasi-periodic brightness variations along their atmospheric path. This phenomenon, which is known as “flickering”, is associated to the entry of spinning non ...

On the Ontology of Composites in Abhidharma Buddhism

Philosophy and Phenomenological Research, Volume 112, Issue 3, Page 679-693, May 2026.
ABSTRACT Abhidharma Buddhism maintains that the only ultimately real (paramārtha) entities in the universe are dharmas, which are simples. What then is the ontological status of composites on this theory? One possibility is that Abhidharma Buddhists deny the reality of composites.

Болід [Bolid]

, 2004
БОЛІ́Д (від грец. βολίς – метальний спис) – яскравий метеор, блиск якого при спостереженні з Землі перевищує блиск планети Венера. Тому яскраві Б. можна спостерігати і вдень. Б. – тверді космічні частинки, які входять у земну атмосферу зі швидкістю від 11 до 72 км/сек. і мають ма... ⚠️ Цей запис містить лише бібліографічні метадані.

Amapari Marker Band Metal‐Enrichments: Potential Mechanisms and Implications for Surface and Subsurface Water and Weathering in Gale Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract NASA's Curiosity rover is exploring a 5 km tall sedimentary mound that is hypothesized to record the transition from a warm and wet (phyllosilicate‐rich) to a cold and drier (sulfate‐rich) Mars. Evidence of magnesium sulfate‐bearing rock has shown that Curiosity has crossed through this phyllosilicate‐sulfate transition.

Historical detection of atmospheric impacts by large bolides using acoustic-gravity waves [PDF]

, 1995
During the period from about 1960 to the early 1980`s a number of large bolides (meteor-fireballs) entered the atmosphere which were sufficiently large to generate blast waves during their drag interaction with the air.

METHODS OF QUALITATIVE ANALYSIS IN THE PROBLEM OF RIGID BODY MOTION IN MEDIUM

, 2011
The present paper describes the application of methods of qualitative analysis in the classical problem of rigid body motion in medium. Three particular problems are used as examples: bolides flight, galloping of aeroelastic constructions, and behavior ...

A Panspermia Origin for Venus Cloud Life

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Decades of study have hinted at the astrobiological potential of Venus's cloud layers. This potential is often cast as stemming from the idea that the Venusian surface was clement in the past. As the climate changed, life then remained in, or perhaps evolved and migrated to, the last habitable niche: the altitudes above ∼50 km with Earth‐like ...
