Abstract:
CCD photometry observations were made of two Hungaria asteroids in 2013 April and May. 4765 Wasserburg was found to be a previously undiscovered binary with a primary period of 3.6231 ± 0.0005 h and a satellite orbital period of 15.97 ± 0.02. What makes this a particularly interesting find is that the asteroid is one member of an asteroid pair (Vokrouhlický and Nesvorný 2008). The suspected Hungaria binary is (12390) 1994 WB1. Data from 2013 indicate the possibility of a satellite with an orbital period of 15.94 h and a primary rotation period of 2.462 h. However, analysis of data from 2008 does not show a satellite and found a period of 15.20 h. At best, 1994 WB1 is an "asteroid of interest."

Detection of Black Holes
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Criteria for Aromaticity and the Hückel 4n + 2 Rule
For the first time, Eric Hückel, a German chemical physicist, derived a set of structural features for a compound to be classified as aromatic. This is now known as Hückel’s rule or the 4n +...
Types of Hypothesis Testing
When the null and alternative hypotheses are stated, it is observed that the null hypothesis is a neutral statement against which the alternative hypothesis is tested. The alternative hypothesis is a claim that instead has a certain direction. If the null hypothesis claims that p = 0.5, the alternative hypothesis would be an opposing statement to this and can be put either p > 0.5, p < 0.5, or p...
