18:45 How can one compensate for light blending effects when measuring the apparent magnitude of Cepheids?This is a non-trivial task, especially if one demands a high level of accuracy. Using the highest resolution telescopes available (such as HST or JWST) is of course helpful, as is switc...

What Is Generative AI (GenAI)? Generative AI (GAI) is the name given to a subset of AI machine learning technologies that have recently developed the ability to rapidly create content in response to text prompts, which can range from short and simple to very long and complex. Different gener...
It is worth noting that current models do not reproduce the correct zero-point (Cassisi et al.2011); however, observational studies have been concentrating on differential effects, and we will limit our discussion to those in this text. ...
It is apparent that althoughthe properties ofG and H are such that the inner-loop feedback system is unstable, because GH=-1, the overall system can be stable by proper selection of the outer-loop feedback gain F. In practice, GH is a function of frequency, and the stability condition...
Differences in rock-age histograms between meteorite parent bodies and the Moon may imply that different sampling biases exist for bodies in the asteroid belt; otherwise, the more straightforward interpretation is that the bombardment that affected the asteroids was more long-lasting than the lunar ...
Traditionally, asymptotics for such sums are expressed in terms of a “main term” of some arithmetic nature, plus an error term that is estimated in magnitude. For instance, a sum such as would be approximated in terms of a main term that vanished (or is negligible) if is “minor arc”...
So long as the latter records are not shown upon a seismogram the former have always been regarded as described, their apparent magnitude being dependent on the multiplication of the writing indices. When, however, in a register we see entries for " vertical motion," neither the measurements ...
