Astroalign: A Python module for astronomical image registration
(Elsevier, 2020-04)
We present an algorithm implemented in the Astroalign Python module for image registration in astronomy. Our module does not rely on WCS information and instead matches three-point asterisms (triangles) on the images to ...

Exoplanet transits observed at OAUNI
(Universidad Nacional de Ingeniería, 2019-06-07)
This work presents the exoplanet transit program developed at OAUNI on the 2016 and 2017 campaigns. Seventeen exoplanet transits were observed and in six of them more than one event was registered. In a couple of cases the ...
A key piece in the exoplanet puzzle
(NLM (Medline), 2018-11)
The detection of a low-mass exoplanet on a relatively wide orbit has implications for models of planetary formation and evolution, and could open the door to a new era of exoplanet characterization.
Moral challenges of going to Mars under the presence of non-intelligent life scenario
(Cambridge University PressGB, 2019)
Much is discussed what would be the ideal position in terms of our ethical treatment with
respect to other forms of life, particularly those that can be discovered in other worlds, in addition
to our role in terms of the ...
Astrobioethics: a brief discussion from the epistemological, religious and societal dimension
(Cambridge University PressGB, 2019)
As astrobiology progresses in its quest to discover life on other planets or to put ourselves in another one, so does its moral problematic. Astrobiology is not only part of natural sciences,
but also deals with direct ...

The Earth's eccentricity in Kepler's refutation of the Tychonic approach to the problem of Mars
(John Wiley & Sons Inc., 2021-11)
In this paper I explain Kepler's procedure for refuting the Ptolemaic-Tychonic approach to the problem of Mars, by using latitudinal observations at Mars's opposition, from Chapter 19 of the Astronomia Nova. This critique ...
On Times and Shadows: The Observational Analemma
(American Association of Physics Teachers, 2018-09)
The observation that the shadows of objects change during the course of the day and also for a fixed time during a year led curious minds to realize that the Sun could be used as a timekeeper. However, the daily motion of ...
Notes on the Transmission of Ptolemy's Almagest and Some Geometrical Mechanisms to the Era of Copernicus
(National Astronomical Research Institute of Thailand, 2019-05)
We trace the transmission of Ptolemy´s Almagest from the time of its composition to Arabic translations, Latin translations, and the Epitome of the Almagest by Peurbach and Regiomontanus. Along the way, Ptolemaic astronomy ...
