The Chemical Composition of Extreme-Velocity Stars
Henrique Reggiani, Alexander P. Ji, Kevin C. Schlaufman +5
Little is known about the origin of the fastest stars in the Galaxy. Our understanding of the Milky Way and surrounding dwarf galaxies chemical evolution history allows us to use t…
Evidence that the Hot Jupiter WASP-77 A b Formed Beyond Its Parent Protoplanetary Disk's H2O Ice Line
Henrique Reggiani, Kevin C. Schlaufman, Brian F. Healy +2
Idealized protoplanetary disk and giant planet formation models have been interpreted to suggest that a giant planet's atmospheric abundances can be used to infer its formation loc…
Searching for new solar twins: The Inti survey for the Northern Sky
J. Y. Galarza, R. López-Valdivia, D. Lorenzo-Oliveira +9
Solar twins are key in different areas of astrophysics, however only just over a hundred were identified and well-studied in the last two decades. In this work, we take advantage o…
The Most Metal-poor Stars in the Inner Bulge
Henrique Reggiani, Kevin C. Schlaufman, Andrew R. Casey +1
The bulge is the oldest component of the Milky Way. Since numerous simulations of Milky Way formation have predicted that the oldest stars at a given metallicity are found on tight…
An empirical metallicity tracer in CEMP and C-normal stars
D. Singh, C. J. Hansen, J. S. Byrgesen +2
Deriving the metallicity, [Fe/H], in low-resolution spectra of carbon-enhanced metal-poor (CEMP) stars is a tedious task that, owing to the large number of line blends, often leads…
The effect of stellar activity on the spectroscopic stellar parameters of the young solar twin HIP 36515
Jhon Yana Galarza, Jorge Meléndez, Diego Lorenzo-Oliveira +7
Spectroscopic equilibrium allows us to obtain precise stellar parameters in Sun-like stars. It relies on the assumption of the iron excitation and ionization equilibrium. However,…
