Mu Draconis
Mu Draconis (μ Draconis, abbreviated Mu Dra, μ Dra) is a multiple star system near the head of the constellation of Draco. With a combined magnitude of 4.92, it is visible to the naked eye. Based on parallax estimates by the Hipparcos spacecraft, it is located approximately 89 light-years from the Sun. The system consists of a single primary star (designated Mu Draconis A, officially named Alrakis from the traditional name of the system), a secondary binary pair (Mu Draconis B) and a further single star (C). B's two components are designated Mu Draconis Ba and Bb. Mu Draconis A and Ba are nearly identical F-type main-sequence stars, with masses of and , respectively. Both have the spectral class of F5V, and have similar apparent magnitude, at 5.66 and 5.69, respectively. The secondary, Mu Draconis B, has a drifting radial velocity, and is itself a spectroscopic binary with an orbital period of 2,270 days.SB9 catalog entry The distance between both st ...

Canopus
Canopus is the brightest star in the southern constellation of Carina (constellation), Carina and the list of brightest stars, second-brightest star in the night sky. It is also Bayer designation, designated α Carinae, which is Latinisation of names, Latinised to Alpha Carinae. With a visual apparent magnitude of −0.74, it is outshone only by Sirius. Located around from the Sun, Canopus is a bright giant of spectral type A9, so it is essentially white when seen with the naked eye. It has a luminosity over 10,000 times the luminosity of the Sun, is eight times as mass of the Sun, massive, and has expanded to 71 times the Sun's radius. Its enlarged photosphere has an effective temperature of around .

In 2017, the company raised a $38 million investment from venture capital firm Canaan Partners as well as Celgene and Pfizer. Arrakis was founded to focus on purposefully discovering RNA-targeting small molecule drugs. Other companies had previously discovered drugs based on RNA-targeting small molecules, however, they were found opportunistically. Arrakis has been able to identify RNA binding sites where small molecule drugs can bind using a bioinformatics tool. The company also utilizes chemical biology tools to confirm whether their compounds are inhibiting RNA cells, and also whether the compounds are specifically ...
