This paper discovers the advantages/disadvantages of different ML models dealing with a particular dataset.

Abstract

This paper begins with the Messier 42 nebula, talking about how different color lights form due to the electron transport in Bohr’s model. How these lights are absorbed by gas and form the absorption spectrum, then how these lights are captured by sensors with the explanation between CCD and CMOS sensors. The history of spectrometer also includes plus the motivation and the reason why people are keeping doing that.

Abstract

1I/2017 U1 (‘Oumuamua), a recently discovered asteroid in a hyperbolic orbit, is likely the first macroscopic object of extrasolar origin identified in the solar system. This paper mainly gives reasons why ‘Oumuamua should be a comet, by explaining three unusual behaviors of ‘Oumuamua which are unnormal ratio, strange track eccentricity, and Peculiar Acceleration; disproving four main hypothesizes to say ʻOumuamua is not a comet, then provide an evidence of reflectivity of surface of ʻOumuamua to prove ʻOumuamua in a regular interval of comet group. Thus, ʻOumuamua is most likely to be a comet.

Abstract

By the recent research and observation, there is a star numbered KIC-8462852 spread a strange flux and decreasing of its brightness without clear periodicity. By the suspects, people have already given and the Drake equation, there is no significant evidence to prove that that is an impossibility; therefore, the inference is there is a possibility to be a Dyson Sphere, which means there is also have a possibility to have another civilization.
