The 2:3:6 quasi-periodic oscillation structure in GRS 1915+105 and cubic subharmonics in the context of relativistic discoseismology
(Monthly Notices of the Royal Astronomical Society 440:3011-3015, 2014-06-01)
We propose a simple toy model to explain the 2:3:6 quasi-periodic oscillation (QPO) structure in GRS 1915+105 and, more generally, the 2:3 QPO structure in XTE J1550−564, GRO J1655−40 and H1743−322. The model exploits the ...
Tsunamis and tsunami prepardness in Costa Rica, Central America
Pacific and Atlantic sides of Costa Rica there are coastal segments characterised by a flat relief, which increases the vulnerability of the coastal communities. In addition to tsunamis originating in the Middle American ...
Tropical precipitation anomalies and d‐excess evolution during El Niño 2014‐16
The last 2014-16 El Niño event was among the three strongest episodes on record. El Niño considerably changes annual and seasonal precipitation across the tropics. Here, we present a unique stable isotope data set of daily ...
Distribución espacial de impactos de eventos hidrometeorológicos en América Central
América Central está expuesta a la ocurrencia de eventos hidrometeorológicos a lo largo del año y los impactos que estos pueden provocar van a estar mayormente localizados en áreas donde las variables tanto naturales como ...
The early rainy season in Central America: the role of thetropical North Atlantic SSTs
We explored the relationship between the precipitation anomalies during May to June as the first peak of the rainy season in the Pacific slope of Central America, and sea surface temperature (SST) fluctuations in the ...
Do Magnetic Fields Destroy Black Hole Accretion Disk g-Modes?
Diskoseismology, the theoretical study of normal-mode oscillations in geometrically thin, optically thick accretion disks, is a strong candidate for explaining some quasi-periodic oscillations in the power spectra of many ...
