Relation between metallicities and spectral energy distributions of Herbig Ae/Be stars. A potential link with planet formation
J. Guzman-Diaz, B. Montesinos, I. Mendigutia +5
(Abridged) The stellar metallicity, [M/H], may have important implications for planet formation. In particular, Kama et al. proposed that the deficit of refractory elements in the…
A rare phosphorus-rich star in an eclipsing binary from TESS
Colin P. Folsom, Mihkel Kama, Tõnis Eenmäe +6
Context: Few exoplanets around hot stars with radiative envelopes have been discovered, although new observations from the TESS mission are improving this. Stars with radiative env…
The TW Hya Rosetta Stone Project II: Spatially resolved emission of formaldehyde hints at low-temperature gas-phase formation
Jeroen Terwisscha van Scheltinga, Michiel R. Hogerheijde, L. Ilsedore Cleeves +15
Formaldehyde (HCO) is an important precursor to organics like methanol (CHOH). It is important to understand the conditions that produce HCO and prebiotic molecules dur…
A precise asteroseismic age and metallicity for HD 139614: a pre-main-sequence star with a protoplanetary disc in Upper-Centaurus Lupus
Simon J. Murphy, Meridith Joyce, Timothy R. Bedding +2
HD\,139614 is known to be a 14-Myr-old, possibly pre-main-sequence star in the Sco-Cen OB association in the Upper Centaurus-Lupus subgroup, with a slightly warped circumstel…
The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars I. Identifying and Characterizing the Protostellar Content of the OMC2-FIR4 and OMC2-FIR3 Regions
John J. Tobin, S. Thomas Megeath, Merel van 't Hoff +31
We present ALMA (0.87~mm) and VLA (9~mm) observations toward OMC2-FIR4 and OMC2-FIR3 within the Orion integral-shaped filament that are thought to be the nearest regions of interme…
Stellar Photospheric Abundances as a Probe of Disks and Planets
Adam S. Jermyn, Mihkel Kama
Protoplanetary disks, debris disks, and disrupted or evaporating planets can all feed accretion onto stars. The photospheric abundances of such stars may then reveal the compositio…
