Solar-like Oscillations [PDF]

Publications of the Astronomical Society of Australia, 2003
AbstractThe five-minute oscillations in the Sun have provided a wealth of information about the solar interior. After many attempts, positive detections of similar oscillations in solar-type stars have now been made. This review discusses the properties of solar-like oscillations, the methods used to observe them, and the results on individual stars ...

Observations of solar-like oscillations [PDF]

Communications in Asteroseismology, 2005
AbstractThe solar-like oscillations are oscillations that are expected to be excited by near-surface convection. Apart from the Sun itself, we now have a number of stars where p-mode solar-like oscillations have been detected. In this paper we present a short presentation of those recently discovered oscillations.

Method for Simulating Solar Panel Oscillations Considering Thermal Shock

Computation
The purpose of this work is to develop an approximate method for simulating the oscillations of a solar panel with consideration of thermal shock, based on a simulated spacecraft system model.

Response of a spaceborne gravitational wave antenna to solar oscillations [PDF]

, 2009
We investigate the possibility of observing very small amplitude low frequency solar oscillations with the proposed laser interferometer space antenna (LISA). For frequencies {nu} below 3x10{sup -4} Hz the dominant contribution is from the near zone time-

Initial Observations of Sunspot Oscillations Excited by Solar Flare

, 2007
Observations of a large solar flare of December 13, 2006, using Solar Optical Telescope (SOT) on Hinode spacecraft revealed high-frequency oscillations excited by the flare in the sunspot chromosphere.

On the Origin of Solar Oscillations [PDF]

, 1998
We have made high-resolution observations of the Sun in which we identify individual sunquakes and see power from these seismic events being pumped into the resonant modes of vibration of the Sun. A typical event lasts about 5 minutes.

Evidence of 5 minute Oscillations from Parker Solar Probe

The Astrophysical Journal Letters
The Sun’s surface vibrates in characteristic 5 minute oscillations, known as p -modes, generated by sound waves trapped within the convection zone. Although these oscillations have long been hypothesized to reach into the solar wind, direct in situ ...

Observation of multiple sausage oscillations in cool postflare loop

, 2008
Using simultaneous high spatial (1.3 arc sec) and temporal (5 and 10 s) resolution H-alpha observations from the 15 cm Solar Tower Telescope at ARIES, we study the oscillations in the relative intensity to explore the possibility of sausage oscillations ...

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

The 11-year solar cycle, the 27-day Sun's rotation and the area of the stratospheric Aleutian high

Meteorologische Zeitschrift, 2001
The effect of the 11-year solar cycle on the 30-hPa geopotential height and temperature fields in the area of the Aleutian high caused by solar activity oscillations resulting from the Sun's rotation (27.2 d) is investigated, applying methods of ...
