The chemical composition of HIP34407/HIP34426 and other twin-star comoving pairs
I. Ramirez, S. Khanal, S. J. Lichon +4
We conducted a high-precision elemental abundance analysis of the twin-star comoving pair HIP34407/HIP34426. With mean error of 0.013 dex in the differential abundances (D[X/H]), a…

The Curious Case of Elemental Abundance Differences in the Dual Hot Jupiter Hosts WASP-94AB
Johanna K. Teske, Sandhya Khanal, Ivan Ramírez
Binary stars provide an ideal laboratory for investigating the potential effects of planet formation on stellar composition. Assuming the stars formed in the same environment/from…

The dissimilar chemical composition of the planet-hosting stars of the XO-2 binary system
I. Ramirez, S. Khanal, P. Aleo +7
Using high-quality spectra of the twin stars in the XO-2 binary system, we have detected significant differences in the chemical composition of their photospheres. The differences…
