Rocky planet engulfment in the binary system HIP 71726-37
J. Yana Galarza, R. López-Valdivia, J. Meléndez +1
Binary stars are supposed to be chemically homogeneous, as they are born from the same molecular cloud. However, high precision chemical abundances show that some binary systems di…
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…
Projected Rotational Velocities and Fundamental Properties of Low-Mass Pre-Main Sequence Stars in the Taurus-Auriga Star Forming Region
Larissa A. Nofi, Christopher M. Johns-Krull, Ricardo López-Valdivia +11
The projected stellar rotational velocity () is critical for our understanding of processes related to the evolution of angular momentum in pre-main sequence stars. We pr…
Compact Disks in a High Resolution ALMA Survey of Dust Structures in the Taurus Molecular Cloud
Feng Long, Gregory J. Herczeg, Daniel Harsono +24
We present a high-resolution (, au, mean sensitivity of Jy~beam at 225 GHz) snapshot survey of 32 protoplanetary disks around young stars with spe…
Effective Temperatures of Low-Mass Stars from High-Resolution H-band Spectroscopy
Ricardo López-Valdivia, Gregory N. Mace, Kimberly R. Sokal +9
High-resolution, near-infrared spectra will be the primary tool for finding and characterizing Earth-like planets around low-mass stars. Yet, the properties of exoplanets can not b…
Mg, Al, Si, Ca, Ti, Fe, and Ni abundance for a sample of solar analogues
Ricardo López-Valdivia, Emanuele Bertone, Miguel Chávez
We report on the determination of chemical abundances of 38 solar analogues, including 11 objects previously identified as super metal-rich stars. We have measured the equivalent w…
