<jats:title>Abstract</jats:title> <jats:p>We report a two-dimensional spectroscopic analysis of massive red spiral galaxies (<jats:italic>M</jats:italic> <jats:sub>*</jats:sub> > 10<jats:sup>10.5</jats:sup> <jats:italic>M</jats:italic> <jats:sub>⊙</jats:sub>) and compare them to blue spiral and red elliptical galaxies above the same mass limit based on the public SDSS DR15 MaNGA observations. We find that the stellar population properties of red spiral galaxies are more similar to those of elliptical galaxies than to blue spiral galaxies. Red spiral galaxies show a shallow mass-weighted age profile, and they have higher stellar metallicity and Mgb/<jats:inline-formula> <jats:tex-math> <?CDATA $\langle \mathrm{Fe}\rangle $?> </jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mo stretchy="false">〈</mml:mo> <mml:mi>Fe</mml:mi> <mml:mo stretchy="false">〉</mml:mo> </mml:math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="apjlab42e5ieqn1.gif" xlink:type="simple" /> </jats:inline-formula> across the whole 1.5<jats:italic>R</jats:italic> <jats:sub>e</jats:sub> as compared to blue spirals, but all these properties are close to those of elliptical galaxies.

The Observability of Vortex-driven Spiral Arms in Protoplanetary Disks: Basic Spiral Properties
Pinghui Huang; Ruobing Dong; Hui Li; Shengtai Li; Jianghui Ji
<jats:title>Abstract</jats:title> <jats:p>Some circumstellar disks are observed to show prominent spiral arms in infrared scattered light or (sub-)millimeter dust continuum. The spirals might be formed from self-gravity, shadows, or planet–disk interactions. Recently, it was hypothesized that massive vortices can drive spiral arms in protoplanetary disks in a way analogous to planets. In this paper, we study the basic properties of vortex-driven spirals by the Rossby Wave Instability in 2D hydrodynamics simulations. We study how the surface density contrast, the number, and the shape of vortex-driven spirals depend on the properties of the vortex. We also compare vortex-driven spirals with those induced by planets. The surface density contrast of vortex-driven spirals in our simulations are comparable to those driven by a sub-thermal mass planet, typically a few to a few tens of Earth masses. In addition, different from the latter, the former is not sensitive to the mass of the vortex. Vortex-driven spiral arms are not expected to be detectable in current scattered light observations, and the prominent spirals observed in scattered light in a few protoplanetary disks, such as SAO 206462 (HD 135344B), MWC 758, and LkH<jats:italic>α</jats:italic> 330, are unlikely to be induced by the candidate vortices in them.</jats:p>
