Time-Distance Inversions: Potential and Limitations
Time-distance analysis is emerging as a powerful diagnostic tool in local helioseismology. By directly measuring propagation times of wave packets between...
Time-resolved Low-resolution Spectra of BLAP-009 and BLAP-014
We present time resolved low resolution spectra of BLAP-009 and BLAP-014 collected with SPRAT on the Liverpool Telescope. The spectra were median-stacked in...
Time-Resolved Rotational Energy Transfer and Spectral Line Broadening in Acetylene. a High Resolution Raman Study.
The quasi-cw stimulated Raman technique is a powerful tool for the determination of collisional broadening and line-mixing parameters, which bear a very direct...
Time-Resolved Spectroscopy of Ir-Geminorem at Quiescence
We present some preliminary results of a spectroscopic study of the cataclysmic system IR Gem at quiescence during two orbital periods. The spectra covered the...
Time-resolved UV spectroscopy of the accretion disk and wind in a super-Eddington black-hole X-ray transient
In October 2018, Swift announced the discovery of a new Galactic X-ray transient, Swift J1858. Just before Sun-angle constraints rendered the system...
Time-scales of Line-broadening Variability in OB Supergiants
Several works have recently shown that there is an important extra line-broadening (usually called macroturbulence) affecting the spectra of O and B Supergiants...
Timing Detection of Eclipsing Binary Planets and Transiting Extrasolar Moons
We investigate the improved detection of extrasolar planets around eclipsing binaries using eclipse minima timing and extrasolar moons around transiting planets...
