On the possibility of chemically driven convection in red giants. Implications for the He-core flash and mixing above the Red Giant Branch Bump
M. Miguel Ocampo, Marcelo M. Miller Bertolami
Turbulent mixing remains one of the primary uncertainties in the modeling of stellar interiors. In stellar evolution simulations, regions where mixing occurs are typically identifi…
Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets II: The Role of Pebble Accretion in Planet Growth within a Global Planet Formation Model
Octavio M. Guilera, Pablo Benitez-Llambay, Marcelo M. Miller Bertolami +1
Although dust constitutes only about 1% of the mass of a protoplanetary disk, recent studies demonstrate that it can exert a significant torque on low- and intermediate-mass planet…
Impact of current uncertainties in the 12C+12C nuclear reaction rate on intermediate-mass stars and massive white dwarfs
Francisco C. De Gerónimo, Marcelo M. Miller Bertolami, Tiara Battich +6
Recent determinations of the total rate of the 12C+12C nuclear reaction show non-negligible differences with the reference reaction rate commonly used in previous stellar simulatio…
Giant planet formation at the pressure maxima of protoplanetary disks II. A hybrid accretion scenario
O. M. Guilera, Zs. Sándor, M. P. Ronco +2
Recent observations of protoplanetary disks have revealed ring-like structures that can be associated to pressure maxima. Pressure maxima are known to be dust collectors and planet…
Hunting white dwarfs at the center of planetary nebulae
Javier Ahumada, Walter Weidmann, Marcelo Miller Bertolami +1
We present Gemini-South observations of nine faint and extended planetary nebulae. Using direct images taken with the spectrograph GMOS, we built the vs. di…
Observations of the Ultraviolet-Bright Star Barnard 29 in the Globular Cluster M13 (NGC 6205)
William V. Dixon, Pierre Chayer, I. N. Reid +1
We have analyzed FUSE, COS, GHRS, and Keck HIRES spectra of the UV-bright star Barnard 29 in M13 (NGC 6205). By comparing the photospheric abundances derived from multiple ionizati…
